    Abstract: A display device including an input sensor having sensing electrodes disposed in a sensing area and signal lines. Each of the signal lines is connected to a corresponding electrode of the sensing electrodes and disposed in the line area. One signal line of the signal lines includes a first portion having a constant width, a second portion disposed outside a corner area of the sensing area, extending from the first portion, and having a width gradually increasing in a direction that is away from the first portion, a third portion extending from the second portion and having a width gradually varying in a direction that is away from the second portion, and a fourth portion extending from the third portion and having a constant width.

    IPC: H01L27/32

    Abstract: An organic light-emitting display apparatus includes a substrate, pixels, a pixel defining layer (PDL), a first via layer, a second via layer, first lines, and a second line. The pixels are arranged on the substrate in a first direction (D1) and a second direction (D2) intersecting one another, and include organic light-emitting diodes (OLEDs). The OLEDs include pixel electrodes (PEs). The PDL covers edges of the PEs and defines light-emitting regions via openings partially exposing the PEs. The first and second via layers are between the PEs and the substrate. The first lines extend in the D2 between the first via layer and the substrate. The second line is between the second and first via layers. The second line at least partially extends around the light-emitting regions. The second line contacts the first lines through via holes. Each via hole is provided every two pixels arranged in the D2.

    Abstract: A display device may include a display panel and an input sensor. Mesh lines of the input sensor may include first mesh lines extending in a first direction and second mesh lines extending in a second direction crossing the first direction. The first mesh lines and the second mesh lines may cross each other at a plurality of cross points. In a unit region of the sensing electrode, first cutting points may be defined in the first mesh lines and the second mesh lines, and second cutting points may be defined in the first mesh lines and the second mesh lines.
