Abstract

A display device includes a display portion defining a display area and including a plurality of pixels, a scan driver disposed in a non-display area that is outside of the display area, and a plurality of scan connection lines. Each of the pixels is connected to a scan line from among a plurality of scan lines and a data line from among a plurality of data lines. The scan connection lines connect the scan driver to the scan lines. Each of the scan connection lines is connected to one of the scan lines through a contact hole disposed in at least one insulating layer, which is disposed between the scan lines and the scan connection lines in a cross-sectional view.
