摘要:
An object of the present invention is to provide an organic light emitting element having a high efficiency and a high quality in which electron and hole injection efficiency of an electrode is reproduced in an insulated or contaminated first electrode. In an organic light emitting display apparatus, a substrate, a first electrode, an insulation film bank formed so as to cover edges of the first electrode, a metal thin film formed on the first electrode and the insulation film bank, an organic light emitting layer, and a second electrode are disposed in the cited order. A lower part of a side face of the insulation film bank takes a reverse tapered shape.
