Abstract

An organic electroluminescence display device and a method of manufacturing the same, configured to prevent IR drop of a second electrode by forming an auxiliary electrode line in an organic electroluminescence display device, are disclosed. The display device is also configured to prevent pixel shrinkage caused by deterioration of an organic electroluminescent layer due to transfer of gases into the organic electroluminescent layer. The out-gassing is prevented by providing a plurality of patterns and/or trenches in the auxiliary electrode line to reduce the contact area between the auxiliary electrode line and the second electrode, thereby lowering heat resistance and optimizing heat transfer during a curing process, and also allowing for removal of remaining gases in an organic film.

Description

technical field [0001] The present invention generally relates to an organic electroluminescent display device and a method of manufacturing the same, and more particularly, to an organic electroluminescent display device equipped with prevention of pixel shrinkage phenomenon caused by degradation of an organic electroluminescent layer. Background technique [0002] Organic electroluminescent display devices, such as organic light emitting diode (OLED) displays, have desirable characteristics such as self-emission, wide viewing angle, fast response, small thickness, low production cost, and high contrast ratio. Therefore, organic electroluminescence display devices, which are next-generation flat panel display devices, have attracted attention. [0003] A typical organic electroluminescent display device includes an anode, a cathode, and an organic electroluminescent layer sandwiched therebetween. Electrons and holes supplied from the respective anodes and cathodes combine ...
