Abstract:
A light-emitter is configured so that at least a hole injection layer and a light-emitting layer are laminated between a first electrode and a second electrode, and the light-emitting layer is formed in an area defined by a bank. In the area defined by the bank, the hole injection layer is formed so as to have a recess in an upper surface thereof. An upper peripheral edge of the recess is covered with a part of the bank. The light-emitting layer is formed with respect to the recess formed in the hole injection layer by a laser transfer method.
