Abstract
A manufacturing method of a top emission organic EL element includes a step of providing an insulating layer on a substrate, a processing step of processing a center area within a region in which the insulating layer is provided, a step of forming a bank on the insulating layer, a lower electrode material applying step, a luminescent material applying step, and an upper transparent electrode forming step. The insulating layer is provided such that a contact angle to a solution to be applied in forming a lower electrode becomes smaller at the center area than the contact angle at a peripheral area within the region.
