Disclosed is a display device capable of reducing the thickness and the weigh thereof. A display device having a touch sensor realizes electrical connection of a routing line and a touch pad via an auxiliary conductive layer, which is connected to the routing line under an encapsulation unit, even if a disconnection fault occurs in the routing line, thereby achieving increased yield and reliability. In addition, through the provision of a touch sensor disposed above the encapsulation unit, a separate attachment process is unnecessary, which results in a simplified manufacturing process and reduced costs.

The present disclosure relates to a display substrate, a display panel, a display device, and a manufacturing method of the display panel. The display substrate display substrate includes a display area, the display area including: a plurality of sides, wherein adjacent sides of the plurality of sides intersect to form a plurality of corners; a first display area having a first pixel density; and a second display area having a second pixel density lower than the first pixel density, wherein the second display area is located in at least one of the corners.

A display device includes a substrate including a display area, a peripheral area, and a pad area, first and second voltage lines, and an island dam. The first voltage line is disposed between a first side of the display area and the pad area, the second voltage line is disposed at other sides of the display area, and the island dam is disposed between the display area and the pad area. The first voltage line includes a first main voltage line, and a first connection unit that protrudes from the first main voltage line and extends toward the pad area. The second voltage line includes a second main voltage line, and a second connection unit that protrudes from an end of the second main voltage line and extends toward the pad area. The island dam extends substantially parallel to the first main voltage line.

A display device includes a substrate including an outer area neighboring a border; and an insulating layer positioned over the substrate and including a plurality of openings positioned over the outer area. The openings are arranged to be spaced from each other in a direction. The display device further includes a wavy line extending in the direction and passing the plurality of openings.

An ink jet process is used to deposit a material layer to a desired thickness. Layout data is converted to per-cell grayscale values, each representing ink volume to be locally delivered. The grayscale values are used to generate a halftone pattern to deliver variable ink volume (and thickness) to the substrate. The halftoning provides for a relatively continuous layer (e.g., without unintended gaps or holes) while providing for variable volume and, thus, contributes to variable ink/material buildup to achieve desired thickness. The ink is jetted as liquid or aerosol that suspends material used to form the material layer, for example, an organic material used to form an encapsulation layer for a flat panel device. The deposited layer is then cured or otherwise finished to complete the process.

An organic light-emitting display apparatus including a substrate; a display unit which defines an active area of the substrate and includes a thin film transistor; concave-convex portions protruded from the substrate in an area outside the active area; and an encapsulation layer which encapsulates the display unit. The thin film transistor includes an active layer, a gate insulating layer on the active layer, a gate electrode, a source electrode, a drain electrode, and an interlayer insulating layer between the gate electrode and the source electrode, and between the gate electrode and the drain electrode. The concave-convex portions include portions of the gate insulating layer and the interlayer insulating layer, and the encapsulation layer covers the concave-convex portions.

A display panel includes a first substrate having a display area and a peripheral area. The display area includes pixels with first output wires connected to the pixels. A first driver is connected to the first output wires and positioned in the peripheral area at a first side of the display area. The first substrate includes a notch portion having a curved edge and the display area has a first display portion and a second display portion with the notch portion therebetween. At least one of the first output wires is a first main line at the first display portion, a second main line at the second display portion, and a first connecting line that is connected to the first main line and the second main line and is at the peripheral area between the first display portion and the second display portion.

A packaging structure with groove includes a substrate, a lower conductive layer, an optical element, a sealing layer and a barrier layer. The lower conductive layer is arranged on one face of the substrate. The optical element is arranged on one face of the lower conductive layer. The upper conductive layer is arranged on one face of the optical element. The packaging structure further comprises a groove defined on an inactive area of the optical element. The sealing layer is arranged on one face of the optical element and on one face of the upper conductive layer. The barrier layer is arranged on one face of the sealing layer. Because the groove is formed on inactive area of the optical element to enhance lateral sealing tightness, extended interface is provided between sealing layer/barrier layer and the substrate, thus enhance the water-resistant and gas-resistant property for package.

A display panel includes: a substrate including a first area, a second area, and a third area located between the first area and the second area; a display layer including a display element located in the second area; a first metal layer located in the third area; an organic insulating layer located on the first metal layer and including at least one contact portion; and a second metal layer located on the organic insulating layer and contacting the first metal layer through the at least one contact portion, in which the second metal layer has a first hole, and the organic insulating layer has a second hole or a first recess corresponding to the first hole, and a residual layer located in the second hole or the first recess and including a part of at least one organic layer overlaps the first metal layer.

Provided is an organic light emitting display device. The organic light emitting display device comprises a substrate including an active area and a non-active area enclosing the active area; a first inorganic encapsulation layer disposed in the active area and at least a part of the non-active area on the substrate; an organic encapsulation layer disposed on the first inorganic encapsulation layer; a second inorganic encapsulation layer disposed on the organic encapsulation layer; and a dam disposed between the first inorganic encapsulation layer and the second inorganic encapsulation layer in the non-active area. At least a part of the organic encapsulation layer is in contact with one surface of the dam.
