Abstract
Provided is an organic EL element including: a first electrode 13; a protection layer 15 that is formed on the first electrode 13 and has an opening portion through which the first electrode 13 is exposed; an insulation layer 17 that is formed on the protection layer 15; an organic layer 19 that is formed over the insulation layer 17 and the first electrode 13 exposed through the opening portion, and includes an emission layer; and a second electrode 21 formed on the organic layer 19, wherein a film thickness of the protection layer 15 is less than that of the organic layer 19.
Claims11
An organic EL element comprising:
- a first electrode;
- a protection layer that is formed on the first electrode and has a first opening portion through which the first electrode is exposed;
- an insulation layer formed on the protection layer and having a second opening portion in a region corresponding to the first opening portion of the protection layer;
- an organic layer that is formed over the insulation layer and the first electrode exposed through the opening portion, and includes an emission layer;
- and
- a second electrode formed on the organic layer,
- wherein a film thickness of the protection layer is less than that of the organic layer.
An organic EL element comprising:
- a first electrode;
- a protection layer formed on the first electrode and having a concave portion;
- an insulation layer formed on the protection layer and having an opening portion through which the protection layer is exposed;
- an organic layer that is formed over the insulation layer and the protection layer exposed through the opening portion of the insulation layer, and includes an emission layer;
- and
- a second electrode formed on the organic layer,
- wherein a depth of the concave portion is less than a film thickness of the organic layer.
