Abstract
A display apparatus includes a substrate including a display area; a first thin film transistor arranged on the display area of the substrate and having a first semiconductor layer including a silicon semiconductor and a first gate electrode insulated from the first semiconductor layer by a first gate insulating layer; a second thin film transistor arranged on the display area of the substrate and having a second semiconductor layer including an oxide semiconductor and a second gate electrode insulated from the second semiconductor layer; and a storage capacitor at least partially overlapping the first thin film transistor and having a lower electrode and an upper electrode, wherein the second semiconductor layer and one of the lower electrode and the upper electrode are arranged on a same layer.
