Array substrate

An array substrate comprising an insulating substrate, pixel circuits arranged in a matrix on the insulating substrate, and video signal lines arranged correspondently with columns which the pixel circuits form, each of the pixel circuits comprising:

• a drive transistor whose source is connected to a power supply terminal;
• a pixel electrode;
• an output control switch connected between a drain of the drive transistor and the pixel electrode;
• a selector switch connected between the drain and the video signal line;
• a diode-connecting switch including switching elements connected in series between the drain and a gate of the drive transistor;
• and
• a capacitor including an electrode connected to the gate,
• wherein, when the array substrate is observed perpendicularly to a main surface of the insulating substrate, a conductive path connecting the drain to the gate of the drive transistor partially overlaps a conductive layer in each of the pixel circuits.
