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.

Claims (17)

1. An organic light emitting diode (OLED) display comprising:

a first substrate;

an organic light emitting element disposed on the first substrate;

a first adhesive layer disposed on the organic light emitting element, covering sides of the organic light emitting element;

a second adhesive layer disposed on the first adhesive layer, and the entirety of which does not contact the organic light emitting element; and

a second substrate disposed on the second adhesive layer,

wherein the first adhesive layer and the second adhesive layer include a thermally curable resin or a photocurable resin, respectively,

wherein the second adhesive layer comprises more than about 5 to about 50 parts by weight of a hygroscopic material based on 100 parts by weight of the thermally curable resin or the photocurable resin, and

wherein the first adhesive layer includes a bisphenol-based epoxy resin as the thermally curable resin or the photocurable resin.

2. The organic light emitting diode (OLED) display of claim 1 ,

wherein the bisphenol-based epoxy resin is a bisphenol A epoxy resin or a bisphenol F epoxy resin.

3. The organic light emitting diode (OLED) display of claim 1 ,

wherein the hygroscopic material includes at least one selected from the group consisting of silica gel (SiO 2 .H 2 O), alumino-silicate beads, montmorillonite, a molecular sieve of zeolite (Na 12 AlO 3 SiO 2 .12H 2 O), activated carbon, alkali metal oxide, alkaline earth metal oxide, metal sulfate, metal halide and metal perchlorate.

4. The organic light emitting diode (OLED) display of claim 3 ,

wherein the alkaline earth metal oxide includes at least one selected from barium oxide (BaO), calcium oxide (CaO), and magnesium oxide (MgO).

5. The organic light emitting diode (OLED) display of claim 1 ,

further comprising a third adhesive layer disposed between the second adhesive layer and the second substrate.
