ABSTRACT:
It is an object of the present invention to provide a display device in which a reverse current sufficient enough to insulate a short-circuited point flows and a transistor using amorphous silicon is used is applied. The display device includes a switching transistor that controls an input of a video signal, a driving transistor that controls a current flowing in a forward direction to a light emitting element, and an AC transistor that controls a current flowing in a reverse direction to the light emitting element; and a reverse bias current can be applied to the light emitting element. Furthermore, the above-described transistors are N-channel transistors.
