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.
