Abstract

An organic light-emitting diode display can include a substrate in which an emission area and a non-emission area are defined; a first transparent conductive layer, a light shielding layer, a buffer layer and a semiconductor layer sequentially laminated on the non-emission area; a gate electrode superposed on the center region of the semiconductor layer, having a gate insulating layer interposed therebetween; a drain electrode coming into contact with one side of the semiconductor layer, having an interlevel insulating layer covering the gate electrode interposed therebetween, and formed of a second transparent conductive layer and a metal layer laminated thereon; a first storage capacitor electrode disposed under the interlevel insulating layer in the emission area and formed of the first transparent conductive layer; and a second storage capacitor electrode superposed on the first storage capacitor electrode, having the interlevel insulating layer interposed therebetween, and formed of the second transparent conductive layer.

Description

technical field [0001] The present invention relates to an organic light emitting diode display having an improved aperture ratio by forming a storage capacitor in a light emitting region using a transparent conductive material and a method of manufacturing the same. In addition, the present invention relates to an organic light emitting diode display and a method of manufacturing the same for simplifying the manufacturing process by reducing the number of mask processes. Background technique [0002] Recently, various flat panel displays having reduced weight and volume compared with cathode ray tubes have been developed. Such flat panel displays include liquid crystal displays (LCDs), field emission displays (FEDs), plasma display panels (PDPs), electroluminescent devices (ELs), and the like. [0003] EL is classified into inorganic EL and organic light emitting diode displays, and is a self-emitting device having the advantages of high response speed, high luminous effic...
