    Abstract: A display device includes a substrate including a display area and a peripheral area disposed around the display area. The peripheral area includes a bending region and a contact region adjacent to the bending region. A first connection line includes a first portion disposed in the contact region, and a second portion disposed in both the bending region and the contact region, and including a first layer and a second layer. At least part of the second layer of the second portion overlaps the first layer of the second portion. In the contact region, the first layer of the second portion is electrically connected to the first portion, and the second layer of the second portion is electrically connected to the first layer of the second portion.

    IPC: H01L27/32

    Abstract: A display device includes a substrate including a pixel region and a peripheral region. A plurality of pixels is disposed in the pixel region of the substrate. Each of the plurality of pixels includes a light emitting element. Data lines and scan lines are connected to each of the plurality of pixels. A power line is configured to supply power to the plurality of pixels. The power line includes a plurality of first conductive lines and a plurality of second conductive lines intersecting the plurality of first conductive lines. The plurality of second conductive lines is arranged in a region between adjacent light emitting elements of the plurality of pixels. At least some of the plurality of second conductive lines extend in a direction oblique to a direction of extension of the data lines or the scan lines.

    Abstract: A display device has a substrate with a first pixel area and a second pixel area smaller than the first pixel area. First pixels in the first pixel area are connected with first scan lines. Second pixels in the second pixel area are connected with second scan lines. A first scan driver supplies a first scan signal to the first scan lines, and a second scan driver supplies a second scan signal to the second scan lines. A first signal line supplies a first driving signal to the first and second scan drivers. The first signal line includes first sub signal line to supply the first driving signal to the first scan driver, a second sub signal line to supply the first driving signal to the second scan driver, and a first load matching resistor connected between the first sub signal line and the second sub signal line.
