Abstract:
Described is an electroluminescent device including an array substrate having a thin-film transistor formed thereon, an organic insulating layer formed on the array substrate having the thin-film transistor formed thereon, barriers disposed on the organic insulating layer, an anode formed on the organic insulating layer between the barriers to thus be electrically connected to the thin-film transistor and configured to cover at least a portion of the barriers, a light-emitting layer formed on the anode, and a cathode formed on the light-emitting layer, thus exhibiting superior emission efficiency and a wide viewing angle. A method of making or manufacturing the electroluminescent device is also described.
