A light-emitting device includes a plurality of unit circuits that are arranged in an element forming region on a substrate, each unit circuit having a light-emitting element that has a first electrode and a second electrode, and a transistor that controls a current flowing in the light-emitting element, a plurality of power lines that are wired in a peripheral region disposed in a periphery of the element forming region so as to supply power having different potentials, a current supply line that is wired to extend from the peripheral region to the element forming region and that is electrically connected to the first electrode via the transistor in each of the unit circuits, and a current supply line protective circuit that is provided in the peripheral region and that has protective elements connected between the current supply line and the plurality of power lines.
