Abstract:
Organic EL elements are 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 a bank defines an area in which the light-emitting layer is to be formed. An inner portion of the hole injection layer is depressed to define a recess. An upper peripheral edge of the recess is covered with a part of the bank.
