摘要:
There is provided a display apparatus. The drive circuit includes a drive transistor configured to control the light emitting unit, a video signal writing transistor configured to control writing of a video signal, and a capacitative element. In the drive transistor, one source/drain region is connected to a current supply line, another source/drain region is connected to the light emitting unit and a first node of the capacitative element, and a gate electrode is connected to a second node of the capacitative element. In the video signal writing transistor, one source/drain region is connected to a data line, another source/drain region is connected to the gate electrode of the drive transistor and the second node of the capacitative element, and a gate electrode is connected to a scanning line. The drive transistor and the video signal writing transistor are different in carrier mobility.
