Abstract:
A liquid crystal display apparatus comprising an active matrix substrate, an opposing substrate, and liquid crystal disposed between the two substrates,wherein the active matrix substrate includes:a transparent substrate,a plurality of scanning lines formed on one surface of the transparent substrate, the one surface being on the side of the opposing substrate,a plurality of signal lines formed in the direction orthogonal to the scanning lines, on the one surface of the transparent substrate while maintaining insulation,pixel electrodes disposed in a plurality of regions surrounded by the scanning and signal lines intersecting with one another, andtransistor devices provided in the regions, each including a gate electrode connected to the scanning lines, a gate insulation film covering the gate electrode, a semiconductor layer provided on the gate insulation film, a source electrode provided on the semiconductor layer and connected to the signal line, and a drain electrode provided on the semiconductor layer and connected to the pixel electrode.wherein the opposing substrate includes:a transparent substrate, anda counter electrode formed on one surface of the transparent substrate on the side of the active matrix substrate,the liquid crystal display apparatus comprising light shielding films covering at least an overlap portion of the semiconductor layer and the source electrode of the transistor devices and an overlap portion of the semiconductor layer and the drain electrode of the transistor devices to shield light incident to the transistor devices, but not covering a channel region.
