Abstract:
1. A thin film transistor (TFT) substrate for a display device, comprising: a gate line; a data line crossing the gate line to define a pixel area; a gate insulating film between the gate and data lines; a TFT at the crossing of the gate and data lines, the TFT including a gate electrode connected to the gate line, a source electrode connected to the data line, a drain electrode opposed to the source electrode, a semiconductor layer between the gate electrode and the source and drain electrodes, and a channel region between the source and drain electrodes; a protective film over the gate line, the data line, and the TFT; a pixel hole defined within the protective film and the gate insulating film, the pixel hole arranged within the pixel area and outside the pixel area; a pixel electrode within the portion of the pixel hole arranged within the pixel area and contacting a side surface of the drain electrode; a first storage capacitor, the first storage capacitor including: a second storage capacitor, the second storage capacitor including:
