Abstract
An organic electroluminescent device. The organic electroluminescent device comprises a first barrier layer disposed on a substrate; organic electroluminescent elements disposed over the first barrier layer and encapsulated with a second barrier layer; and a getter layer disposed between the first and second barrier layers. Each of the first and second barrier layers includes an organic layer and an inorganic layer covering the top and sidewall surfaces of the organic layer, thus providing stacked inorganic sidewalls to hinder moisture and oxygen.
Claims17
An organic electroluminescent device, comprising:
- a substrate;
- a first barrier layer disposed on the substrate;
- an organic electroluminescent element disposed over the first barrier layer;
- a second barrier layer disposed over and encapsulating the organic electroluminescent element;
- and
- a first getter layer disposed between the organic electroluminescent element and the second barrier layer, wherein the first getter layer directly wraps around the top and sidewall surfaces of the organic electroluminescent element, and the first getter layer comprises a polymer matrix and a plurality of getter particles dispersed in the polymer matrix,
- wherein each of the first and the second barrier layers includes an organic layer and an inorganic layer covering the top and sidewall surfaces of the organic layer, such that the inorganic layers of the first and the second barrier layers are adjoined at the sidewalls.
