Abstract: A display apparatus includes a first transistor, a first pixel electrode, a second transistor, and a second pixel electrode. The first transistor includes a first drain electrode. The first pixel electrode is positioned between an edge of the display apparatus and a center of the display apparatus and includes a first recessed structure. The first recessed structure directly contacts the first drain electrode. The second transistor includes a second drain electrode. The second pixel electrode is positioned between the edge of the display apparatus and the first pixel electrode and includes at least one recessed structure. The at least one recessed structure includes a second recessed structure. The second recessed structure directly contacts the second drain electrode. A total maximum width of the at least one recessed structure is greater than a maximum width of the first recessed structure.
