Abstract
The display element includes: a current-driven light-emitting unit; a capacitor unit including a first capacitor and a second capacitor; an n-channel driving transistor that causes a current corresponding to a voltage held by the capacitor unit to flow through the light-emitting unit; and a first switching transistor that writes a video signal voltage to the capacitor unit. In a state in which the first capacitor holds a voltage corresponding to a threshold voltage of the driving transistor, a video signal voltage is written to the second capacitor through the first switching transistor in a conducting state.
