Abstract:
1. A panel comprising a thin film transistor, the panel comprising: a substrate; a first electrode on the substrate; a first insulating layer on the first electrode; an oxide semiconductor pattern on the first insulating layer, the oxide semiconductor pattern comprising a channel region; an etch stopper on the oxide semiconductor pattern; and a conductive layer on the substrate, the conductive layer comprising a signal line, a second electrode, and a third electrode, wherein the second electrode and the third electrode are disposed on the etch stopper and directly on the oxide semiconductor pattern, wherein except for the channel region of the oxide semiconductor pattern, sidewalls of the oxide semiconductor pattern substantially coincide with sidewalls of the signal line, the second electrode, and the third electrode, and wherein a work function of the second electrode and the third electrode is lower than a work function of the oxide semiconductor pattern.
