    Abstract: A display device comprises a substrate having an active region and an outer region surrounding the active region, a substrate hole provided in the active region of the substrate, a separation area positioned between the active region and the substrate hole, a first thin film transistor provided in the active region, a first interlayer insulating layer covering a first gate electrode of the first thin film transistor, a first intermediate insulating layer on the first interlayer insulating layer, a second thin film transistor positioned on the first intermediate insulating layer, a second interlayer insulating layer covering a second gate electrode of the second thin film transistor and extending to the separation area, and a second intermediate insulating layer covering an upper portion of the second interlayer insulating layer and extending to the separation area. The second intermediate insulating layer has different thicknesses in the active region and the separation area.

    Abstract: A display device comprises a display panel in which a plurality of subpixels are disposed, wherein the plurality of subpixels include a first subpixel, a second subpixel, a third subpixel, and a fourth subpixel that are sequentially disposed in a single row or column; a gate driver disposed on the display panel and supplying a scanning signal to the plurality of subpixels; a first island pattern disposed in each area of the first subpixel and the third subpixel; a second island pattern disposed in each area of the second subpixel and the fourth subpixel; a first connection line electrically connecting the first island pattern disposed in the area of the first subpixel and the first island pattern disposed in the area of the third subpixel; and a second connection line electrically connecting second island pattern disposed in the area of the second subpixel and the second island pattern disposed in the area of the fourth subpixel, wherein the first connection line and the second connection line are electrically disconnected from each other, and the gate driver independently drives the first connection line and the second connection line.
