Abstract:
1. An organic light emitting diode display device (OLED display device) comprising: a substrate; a semiconductor layer disposed on the substrate, and comprising source and drain regions and a channel region that are formed using metal induced lateral crystallization (MILC); a gate insulating layer electrically insulating the semiconductor layer; a gate electrode disposed on the gate insulating layer; an interlayer insulating layer electrically insulating the gate electrode; a thin film transistor (TFT) comprising the semiconductor layer and source and drain electrodes that are electrically connected to the source and drain regions of the semiconductor layer; a first capacitor electrode disposed on a region of the substrate to be spaced apart from the TFT, and formed using a metal induced crystallization (MIC), the gate insulating layer electrically insulating the first capacitor electrode; a second capacitor electrode disposed on the gate insulating layer; a planarization layer disposed on the TFT and the capacitor; a first electrode disposed on the planarization layer; a pixel defining layer disposed on the first electrode; an organic layer disposed on the first electrode and the pixel defining layer, and comprising an emission layer; and a second electrode disposed on the organic layer, wherein the first capacitor electrode further comprises a metal layer comprising a metal silicide.
