Patent ID: 8852977

Claim:
A method for manufacturing a light-emitter including a first electrode, a laminate disposed on the first electrode that includes a charge injection transport layer and a light-emitting layer, a second electrode disposed on the laminate, and a bank that defines an area in which the light-emitting layer is to be formed, the method comprising: forming the charge injection transport layer; forming a bank material layer that forms the bank on the charge injection transport layer; removing a portion of the bank material layer to partially expose the charge injection transport layer; heat-treating a remaining portion of the bank material layer; and forming the light-emitting layer on an exposed surface of the charge injection transport layer after the heat treatment, wherein the charge injection transport layer is made from a material that is eroded when exposed to a liquid used while the charge injection transport layer is partially exposed, the charge injection transport layer having a recess in the exposed surface thereof so that a bottom of the recess is lower than a bottom surface of the remaining portion of the bank material layer, the recess being formed by the exposed surface eroded by the liquid, the remaining portion of the bank material layer being made fluid so that the bank material layer extends to cover an upper peripheral edge of the recess, the light-emitting layer being formed by using a laser transfer method.
