Abstract:
A display element includes a light-emitting unit of a current drive type, and a drive unit that drives the light-emitting unit, in which the drive unit includes a capacitance unit, a drive transistor that causes a current corresponding to a voltage held by the capacitance unit to flow through the light-emitting unit, and a write transistor that writes a signal voltage to the capacitance unit, the drive transistor and the write transistor are formed in a state of being separated by an element isolation region, on a semiconductor substrate, and a capacitance generated in a portion where the drive transistor and the write transistor face each other through the element isolation region functions as at least a part of the capacitance unit.
