  • Patent number: 7907224
    Abstract: One embodiment of the present invention is an image display device including a substantially transparent substrate, a color filter layer formed on the substantially transparent substrate and a substantially transparent semiconductor circuit formed on the color filter layer. The circuit includes a substantially transparent thin film transistor including a source electrode, a drain electrode, a gate insulating film, a gate electrode and a semiconductor active layer comprised of a metal oxide. The semiconductor active layer has a thickness of 10 nm-35 nm. The circuit also includes a wiring made of a substantially transparent conductive material, the wiring having a electric contact point with the substantially transparent thin film transistor.
