Abstract

An electroluminescence display device is disclosed, which may use a polysilicon thin film transistor and an oxide thin film transistor together by using a dual line with respect to a plurality of switching transistors arranged on the same line. The electroluminescence display device includes a first active layer; a first gate line arranged on the first active layer and intersecting the first active layer; a second active layer forming a channel different from that of the first active layer, arranged on the first gate line; and a second gate line arranged on the second active layer and intersecting the second active layer. The first gate line and the second gate line are overlapped with each other, and the first gate line and the second gate line supply the same gate signal.
