THIN FILM TRANSISTOR AND DISPLAY DEVICE USING THE SAME
Abstract:
A display panel including an oxide thin film transistor is disclosed. In the oxide thin film transistor, a part of the active layer between a source region and a drain region is covered with an etch stopper layer, and the etch stopper layer is partially covered by the first electrode and the second electrode of the oxide thin film transistor. The length in which the etch stopper layer is overlapped by the second electrode is greater than the length in which the etch stopper layer is overlapped by the first electrode to suppress threshold voltage shift in the oxide thin film transistor.
