Display element, display device, and electronic device

A display device comprising

• display elements arrayed in a two-dimensional matrix, wherein
• the display elements each include a light-emitting unit of a current drive type, and a drive unit that drives the light-emitting unit,
• 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.
