Patent ID: 8395569

Claim:
A dual panel type organic electroluminescent display device, comprising: a first and a second substrates facing each other and having a pixel region and a border region at a boundary of the pixel region; a first electrode in the pixel region and the border region and on the first substrate; a first and a second walls in the border region and on the first electrode, the first and the second walls spaced apart from each other, each of the first and the second walls having a reverse-taper shape with respect to the first substrate and a first and a second side surfaces, wherein the second side surface of the first wall faces the second side surface of the second wall, and the first side surfaces of the first and the second walls are respectively opposite to the second side surfaces of the first and the second walls; a first pattern covering the first side surfaces of the first and the second walls and having a first height from the first electrode; a second pattern covering an upper surface of one of the first and the second walls and having a second height from the first electrode greater than the first height; an organic emitting layer on the first electrode, the second pattern and the first pattern on the other one of the first and the second walls; a second electrode on the organic emitting layer, a portion of the second electrode covering an upper surface of the organic emitting layer on the second pattern; a switching thin film transistor in the pixel region and on the second substrate; a driving thin film transistor in the pixel region and on the second substrate, the driving thin film transistor connected to the switching thin film transistor; and a connection electrode on the second substrate and connected to the driving TFT and the portion of the second electrode, wherein a first portion of the second electrode corresponding to the first wall and a second portion of the second electrode corresponding to the second wall have a difference in a distance from the second substrate, and the organic emitting layer contacts an upper surface of the other one of the first and the second walls.
