Abstract:
An active matrix substrate used in a display device comprising:a gate line;a source line;a thin film transistor (TFT) provided in the vicinity of an intersection between the gate line and the source line, the thin film transistor including a gate electrode connected to the gate line, a source electrode connected to the source line, a drain electrode, and a channel region;an interlayer insulating film having a planer surface provided over the thin film transistor, the gate line, and the source line, wherein the interlayer insulating film is an organic film;a transparent pixel electrode provided on the planer surface of the interlayer insulting film and connected to the drain electrode via a contact hole formed in the interlayer insulating film, wherein the pixel electrode is formed of a transparent conductive material through which light passes during operation of the display device and the pixel electrodes having edges overlapping the gate and source lines; anda conductive layer formed over the channel region of the thin film transistor via the interlayer insulating film to minimize deterioration of an OFF-characteristic of the thin film transistor resulting from extended application of voltage to the thin film transistor.
