摘要： A display device includes: a substrate; a first signal line and a second signal line disposed on the substrate; and an interlayer-insulating layer disposed between the first signal line and the second signal line. The interlayer-insulating layer includes a first portion and a second portion having different heights measured from a surface of the substrate along a first direction that is perpendicular to the surface of the substrate, an upper surface of the first portion of the interlayer-insulating layer is flat, a surface of the second portion of the interlayer-insulating layer is flat, a height of the first portion is lower than a height of the second portion, the interlayer-insulating layer defines a contact hole, and the contact hole is disposed in the first portion of the interlayer-insulating layer.
