Problems solved by technology

As a result, there are problems in that the manufacturing process of the organic light emitting display is complicated and the cost is increased
However, since the N + impurity doping process, so when forming the gate electrode, the doped N + Impurities can diffuse unnecessarily
As a result, the problem is that the performance and reliability of CMOS TFTs are degraded, thereby reducing the display quality of OLEDs

Abstract

In an organic light emitting display, the process of forming a storage capacitor is simplified, and deterioration of the properties and the reliability of the TFT is prevented. The organic light emitting display includes a substrate, a thin film transistor formed on one portion of the substrate, the thin film transistor having an active layer, a gate electrode, a gate insulating layer interposed between the active layer and the gate electrode, and a storage capacitor formed on another portion of the substrate. The storage capacitor has a first electrode formed on the same surface as the active layer, and a second electrode formed on the same surface as the gate electrode, with the gate insulating layer being interposed between the first electrode and the second electrode. The active layer and the first electrode are made of an intrinsic polysilicon layer.

Description

technical field [0001] The present invention relates to an organic light emitting display, and more particularly, to an organic light emitting display having a storage capacitor and a method of manufacturing the organic light emitting display. Background technique [0002] Unlike cathode ray tubes (CRTs), which are bulky and operate with high voltage, display devices such as organic light emitting displays and liquid crystal displays are thin and operate with low voltage, which are being widely used as next generation display devices. [0003] Specifically, an organic light-emitting display is a self-emission display device in which electrons and holes injected into an organic material through an anode and a cathode recombine to generate excitons, and as a function of the energy of the generated excitons As a result, light with a specific wavelength is emitted. Therefore, since the organic light emitting display does not require a separate light source such as a backlight u...
