Abstract
A light-emitting device includes a drive transistor for controlling the quantity of current supplied to a light-emitting element, a capacitor element electrically connected to a gate electrode of the drive transistor, and an electrical continuity portion for electrically connecting the drive transistor and the light-emitting element, these elements being disposed on a substrate. The electrical continuity portion is disposed on the side opposite to the capacitor element with the drive transistor disposed therebetween.
