Abstract
Provided is an organic electroluminescence display device including a substrate, a first electrode disposed on the substrate, a pixel defining layer disposed on the first electrode and having an opening defined therein for exposing at least a part of the first electrode, an organic layer disposed on the first electrode exposed by the opening and including a light emitting layer, and a second electrode disposed on the organic layer, wherein the pixel defining layer includes a base resin and a hindered amine light stabilizer (HALS).
Claims10
An organic electroluminescence display device comprising:
- a substrate;
- a first electrode disposed on the substrate;
- a pixel defining layer disposed on a portion of the first electrode and having an opening defined therein for exposing at least another portion of the first electrode, the opening of the pixel defining layer defining a pixel;
- an organic layer disposed on the first electrode exposed by the opening and comprising a light emitting layer, the organic layer being in the pixel defined by the opening of the pixel defining layer;
- a second electrode disposed on the organic layer;
- and
- a passivation layer disposed between the substrate and the first electrode;
- wherein the pixel defining layer comprises a base resin and a hindered amine light stabilizer (HALS),
- wherein the pixel defining layer is a partition wall, and
- wherein the pixel defining layer which comprises the hindered amine light stabilizer (HALS) is disposed on the same layer as the organic layer comprising the emission layer.
