A hole injection layer and a light-emitting layer are laminated between a first electrode and a second electrode of a light emitter. A bank defines an area in which the light-emitting layer is to be formed. In the area defined by the bank, a hole injection layer has a recess in an upper surface thereof. An upper peripheral edge of the recess is covered with a part of the bank.
