Abstract
Disclosed is an organic light emitting diode (OLED) display comprising a substrate; an organic light emitting element disposed on the substrate; an encapsulation substrate disposed on the organic light emitting element; and an adhesive layer formed on the substrate, covering the organic light emitting element, and bonding the substrate on which the organic light emitting element is formed with the encapsulation substrate.
Claims11
An organic light emitting diode (OLED) display comprising
- a substrate;
- an organic light emitting element disposed on the substrate;
- an encapsulation substrate disposed on the organic light emitting element;
- and
- an adhesive layer formed between the substrate and the encapsulation substrate, covering the organic light emitting element, and bonding the substrate on which the organic light emitting element is formed with the encapsulation substrate,
- wherein the adhesive layer is formed by sequentially accumulating:
- a) a first filling adhesive layer,
- b) a hygroscopic adhesive layer not contacting either of the organic light emitting element or the encapsulation substrate and
- c) a second filling adhesive layer;
- wherein the adhesive layer includes thermally curable resin or photocurable resin;
- and
- wherein the first filling adhesive layer, the hygroscopic adhesive layer and the second filling adhesive layer include the same kind of thermally curable resin or photocurable resin so that the adhesive layer is formed as one integrated sheet without forming an interface between the layers.
