Patent ID: 7312571

Claim:
An organic electroluminescent device, comprising: a substrate including a thin film transistor having a pixel area defined thereon; a first insulating layer having a plurality of uneven patterns formed on the thin film transistor and the substrate; a first electrode formed on a predetermined portion of the first insulating layer to electrically connect to the thin film transistor; a second insulating layer formed on a predetermined portion of the first insulating layer to contact the first electrode in a vicinity of a corner of the pixel area; a counter electrode formed on the second insulating layer including the vicinity of the corner of the pixel area; an electroluminescent layer formed on the first electrode at the pixel area; and a second electrode formed on the electroluminescent layer and the counter electrode, wherein the second insulating layer and the counter electrode include a projected part to project into the pixel area independently, wherein the projected parts of the second insulating layer and the counter electrode are located in the vicinity of the corner of the pixel area, and overlap each other.
