A method of manufacturing a display panel includes fabricating a display portion on a glass substrate; forming a barrier layer on the glass substrate outside the display portion; forming an encapsulation film on the barrier layer and the display portion; and obtaining a panel area by removing the barrier layer and the encapsulation film outside a predetermined limited area on the glass substrate. The predetermined limited area corresponds to the display portion.

A method of manufacturing a display panel includes fabricating a display portion on a glass substrate; adhering a protection film on the glass substrate outside the display portion, and the protection film having an opening accommodating the display portion; forming an encapsulation film on the protection film and the display portion; and obtaining a panel area by removing the protection film and the encapsulation film outside a predetermined limited area on the glass substrate. The predetermined limited area corresponds to the display portion.

A display device includes a substrate including a display area and a non-display area; a pixel circuit layer disposed on a first surface of the substrate and including at least one transistor; a display element layer disposed on the pixel circuit layer and including a light emitting element; a thin film encapsulation layer disposed on the display element layer; and a dummy unit disposed in the non-display area and disposed on an edge portion of the substrate. The dummy unit includes a transparent conductive material.

An organic light emitting display device including a dam structure disposed in a non-display area of a substrate and an alignment mark disposed outside the dam structure. The alignment mark is not covered by, and does not overlap with, the dam structure, because the alignment mark is disposed outside the dame structure. Thus, a scribing process may be performed smoothly.

An apparatus for manufacturing a display apparatus is provided. The apparatus includes a stage that has a first surface and a second surface. A display substrate is arranged on the first surface, and the second surface is opposite to the first surface. The apparatus also includes a jig facing the second surface, a heat transfer unit arranged on the jig and including a protrusion pin protruding toward the second surface, and a laser unit configured to irradiate a laser beam to the heat transfer unit.

A mother substrate for a display panel includes a first substrate including a panel area and a peripheral area surrounding at least one side of the panel area, a second substrate disposed on a first surface of the first substrate, a first support member disposed on a second surface of the first substrate opposite to the first surface of the first substrate in a first direction, the first support member overlapping the panel area of the first substrate in a plan view, and a second support member disposed on the second surface of the first substrate, the second support member overlapping the peripheral area of the first substrate in a plan view.

Processes for producing an OLED screen with a reduced, minimized, or eliminated bezel section surrounding the display are. The circuitry (206) of the display screen is moved to beneath the OLED (212) and transistor layers (210). The screens with the reduced sized may be installed in an aircraft, and, two or more of the OLED screens with reduced sized may be positioned adjacent to each other so as to form an array.

A display panel is provided. The display panel includes: a substrate, and a light-emitting device, an encapsulation layer and an auxiliary barrier which are disposed on the substrate. The light-emitting device is disposed in a display area, and the auxiliary barrier is disposed in a non-display area. A height of the auxiliary barrier is greater than a distance between a side of the encapsulation layer away from the substrate and the substrate.

A display apparatus includes a flexible substrate, a thin-film transistor unit, and a light-emitting unit. The flexible substrate includes a display area has a first area, a peripheral area which is adjacent to the display area, and a first penetrating portion corresponding to the first area. The thin-film transistor unit is in the display area and at least a portion of the peripheral area. The thin-film transistor unit includes a thin-film transistor and an insulation layer and has a second penetrating portion at a location corresponding to the first penetrating portion. The light-emitting unit is on the thin-film transistor unit and includes a pixel electrode, an intermediate layer including an emission layer, and a counter electrode.

A display device according to some exemplary embodiment includes: a display area; a non-display area surrounding the display area and including a sealing area; a first substrate including a center portion including a portion in the display area and an external portion including a portion in the sealing area; a second substrate including a center portion including a portion in the display area and an external portion including a portion in the sealing area; and a sealing portion between the first substrate and the second substrate and in the sealing area, wherein a thickness of the center portion of the first substrate is different from a thickness of the external portion of the first substrate, and a thickness of the center portion of the second substrate is different from a thickness of the external portion of the second substrate.
