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.
