Abstract:
A display apparatus including: a first thin-film transistor and a second thin-film transistor on a substrate, wherein the first thin-film transistor includes a first electrode layer, and the second thin-film transistor includes a second electrode layer; an insulating layer having a first contact hole and a second contact hole respectively exposing the first electrode layer and the second electrode layer; a first pixel electrode connected to the first thin-film transistor through the first contact hole; and a second pixel electrode connected to the second thin-film transistor through the second contact hole. A top surface of the first pixel electrode overlapping the first electrode layer in the first contact hole has a first step facing a first direction, and a top surface of the second pixel electrode overlapping the second electrode layer in the second contact hole has a second step facing a second direction opposite to the first direction.
