Abstract
An organic electroluminescent device includes a plurality walls intersecting with anode electrode layers and a plurality of mask supporting members formed between the anode electrode layers. A method for manufacturing the organic electroluminescent device includes: forming a plurality of anode electrode layers on a substrate; forming an insulating layer on the area except for predetermined areas of the anode electrode layers; forming a plurality of walls intersecting with each of the anode electrode layers; forming a plurality of mask supporting members, each formed on a predetermined area between the anode electrode layers; and forming organic EL layers and a plurality of cathode electrode layers by using a mask. The plurality of mask supporting members assists in preventing the walls and organic material layers from being damaged by the mask during the process of forming the organic EL layers and cathode electrode layers.
