Abstract: A thin film transistor and a display apparatus including the thin film transistor are discussed. The thin film transistor can include a light shielding layer on at least a portion of a substrate, a buffer layer on the light shielding layer, an active layer on the buffer layer, a gate insulating layer on the active layer, and a gate electrode on the gate insulating layer. A gate electrode opening can be disposed in the gate electrode and is formed by removing a portion of the gate electrode.

Abstract: A display apparatus comprises a first signal line on a substrate, a second signal line intersecting with the first signal line, a first gate electrode, a first source electrode, a first drain electrode, and a second gate electrode disposed on the same layer as that of the first signal line, a first active layer spaced apart from the first gate electrode and partially overlapped with the first gate electrode, a second active layer spaced apart from the second gate electrode and partially overlapped with the second gate electrode, and a first electrode of a display device connected with the second active layer.
