A display device includes a display panel, a first line, a second line, a first driver, and a second driver. The display panel includes a first display area, a second display area, a third display area, and a fourth display area, which are sequentially arranged. The first display area and/or the second display area may be flexible. The second driver corresponds to the fourth display area, provides a first data voltage through the second line to the first display area during a first period, and provides a fourth data voltage to the fourth display area during a second period immediately following the first period. The first driver corresponds to the third display area, provides a second data voltage through the first line to the second display area during the second period, and provides a third data voltage to the third display area during the first period.

A display device includes a base layer, a first electrode on the base layer, a pixel-defining layer in which an opening exposing an upper surface of the first electrode is defined, a protective layer overlapping the pixel-defining layer and between the pixel-defining layer and the first electrode, a functional layer on the first electrode in the opening, an auxiliary electrode on an upper surface of the pixel-defining layer, and a second electrode on the functional layer and the auxiliary electrode.

A method of fabricating a conductive pattern includes forming a conductive metal material layer and a conductive capping material layer on a substrate, forming a photoresist pattern as an etching mask on the conductive capping material layer, forming a first conductive capping pattern by etching the conductive capping material layer with a first etchant, forming a conductive metal layer and a second conductive capping pattern by etching the conductive metal material layer and the first conductive capping pattern with a second etchant, and forming a conductive capping layer by etching the second conductive capping pattern with a third etchant.

The present disclosure relates to a display panel and a repair method thereof. The display panel includes a plurality of pixel circuits in which an emission region, through which light from a light-emitting element is emitted, is defined, a power line configured to apply a pixel driving voltage to the pixel circuits, a reference voltage line to which a reference voltage lower than the pixel driving voltage is applied, and a branch line connected to the reference voltage line to apply the reference voltage to one or more of the pixel circuits. At least a portion of the branch line includes a partially metalized semiconductor layer.

A display apparatus having a connection electrode which crosses a bending area may be provided. The connection electrode may be disposed on a device substrate including a bending area between a display area and a pad area. The connection electrode may connect the display area and the pad area across the bending area. The connection electrode may have a stacked structure of the lower connecting electrode and the upper connecting electrode. A light-emitting device, an encapsulating element and a touch electrode may be sequentially stacked on the display area of the device substrate. The upper connecting electrode may include the same material as the touch electrode. Thus, in the display apparatus, the disconnection of the connection electrode due to bending stress and external impact may be reduced.

A circuit board includes a board, first connection pads disposed on the board and arranged in a first direction, second connection pads disposed on the board and arranged in the first direction, the second connection pads spaced apart from the first connection pads in a second direction perpendicular to the first direction, and a driving chip disposed on the board between the first connection pads and the second connection pads. Each of the first connection pads includes a first conductive layer disposed on the board, a second conductive layer which entirely overlaps with the first conductive layer in a plan view, is disposed on the first conductive layer and is formed of a different material from that of the first conductive layer, and a third conductive layer entirely overlapping with the second conductive layer and disposed on the second conductive layer.

A display panel includes an array substrate, a protective cover, a fingerprint identification circuit, and an optical structure. The array substrate and the protective cover are disposed oppositely, where the protective cover is located at a light exiting side of the array substrate. The fingerprint identification circuit is located at a side of the array substrate facing away or toward the protective cover and is configured to receive detection light and perform a fingerprint detection according to the detection light. The optical structure is located at a side of the protective cover facing away from the array substrate and is configured to increase a reflection amount of the detection light received by the fingerprint identification circuit.

A transparent display panel and a transparent display device including the same are disclosed. In a transparent display panel, a VSS voltage line does not surround an outer periphery of a display region. Rather, upper and lower VSS voltage lines respectively disposed on upper and lower sides to the display region are electrically connected to each other via at least one VSS voltage connection line extending across the display region. Thus, left and right non-transparent and thick VSS voltage lines disposed on the left and right sides to the display region may be omitted. Thus, a transparent region of the transparent display panel and a bezel of a transparent display device may be increased or maximized or the bezel thereof may be made slim.

A display device includes a display panel including panel pads adjacent to the side surface of a display panel; connection pads disposed on the side surface of the display panel and connected to the panel pads; and a circuit board disposed on the side surface of the display panel and including lead signal lines directly bonded to the connection pads, wherein the connection pads include a first connection pad, a second connection pad disposed on the first connection pad, and a third connection pad disposed on the second connection pad, and the first connection pad is in contact with corresponding one of the panel pads, and the third connection pad is directly bonded to corresponding one of the lead signal lines.
