Abstract: A display apparatus includes a first transistor including a first semiconductor layer and a first electrode that at least partially overlaps the first semiconductor layer. A first capacitor includes the first electrode and a second electrode that at least partially overlaps the first electrode. A second capacitor includes the second electrode and a third electrode that at least partially overlaps the second electrode. A first data line is configured to transfer a data voltage therethrough. First and second scan lines are configured to transfer first and second scan signals therethrough, respectively. A second transistor connects the first data line to the second electrode in response to the first scan signal. A third transistor connects the first electrode to a drain of the first transistor in response to the second scan signal.

Abstract: A display device includes a first pixel and a second pixel. A light emitting element and a pixel circuit of the second pixel are in a second area. The first pixel includes a silicon transistor and an oxide transistor in the second area. The first pixel includes a connection line that electrically connects one of the silicon transistor and the oxide transistor to a light emitting element in a first area. The connection line is on the same layer as the oxide semiconductor pattern and includes a transparent conductive oxide.
