Abstract
A light emitting device includes a pixel defining layer including a plurality of pixel defining layer elements, on a substrate; a first electrode in a space defined by the substrate and the pixel defining layer; a light emitting layer in a space defined by the first electrode and the pixel defining layer; and a second electrode on the light emitting layer and the pixel defining layer. The second electrode includes a plurality of layers, and an insulating layer between the plurality of layers, overlapping the light emitting layer, and exposing a layer among the plurality of layers in an area corresponding to the pixel defining layer.
Claims14
A light emitting device, comprising:
- a pixel defining layer comprising a plurality of pixel defining layer elements, on a substrate;
- a first electrode in a space defined by the substrate and the pixel defining layer;
- a light emitting layer in a space defined by the first electrode and the pixel defining layer;
- and
- a second electrode on the light emitting layer and the pixel defining layer, and comprising:
- a plurality of layers, and
- an insulating layer between the plurality of layers and overlapping the light emitting layer in an area adjacent to the pixel defining layer elements, and exposing a layer among the plurality of layers in an area corresponding to the pixel defining layer elements.
An organic electroluminescence device, comprising:
- a pixel defining layer comprising a plurality of pixel defining layer elements on a transparent substrate, and having an electrical insulating property;
- an anode on the transparent substrate and in a space defined by the transparent substrate and the pixel defining layer;
- an organic light emitting layer in a space defined by the anode and the pixel defining layer;
- and
- a cathode on the organic light emitting layer, and comprising:
- a first metallic layer adjacent to the organic light emitting layer, and
- a second metallic layer having a cross-sectional thickness larger than that of the first metallic layer, and spaced apart from the organic light emitting layer, wherein the first metallic layer is between the second metallic layer and the organic light emitting layer,
- wherein the anode is disposed between the transparent substrate and the cathode.
