DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a light-emitting display device capable of improving an opening ratio in pixels including thin film transistors using oxide semiconductors.

SOLUTION: The light-emitting display device has a plurality of pixels each having a thin-film transistor and a light-emitting element. Each pixel is electrically connected to a first wiring that functions as a scanning line. The thin-film transistor has an oxide semiconductor layer that is provided on the first wiring with a gate insulating film therebetween. The oxide semiconductor layer is provided to extend off the region where the first wiring is provided, with the light-emitting element being superimposed on the oxide semiconductor layer.
