A thin-film transistor of an inverted-staggered structure includes a semiconductor layer with a channel portion, a protective insulating film extending on the channel portion of the semiconductor layer, a source electrode, and a drain electrode. The protective insulating film has a rectangular shape with four corners, and each of two of the corners overlaps one of the source electrode and the drain electrode while two others of the corners overlap neither the source electrode nor the drain electrode. The thin-film transistor may be modified so that one of the corners overlaps one of the source electrode and the drain electrode while three others of the corners overlap neither the source electrode nor the drain electrode.

摘要:
Disclosed is a liquid crystal display capable of ensuring brightness necessary for achieving satisfactory display by increasing ratio of light-emitting time to one frame period. A liquid crystal display is adapted to have a period (non-video signal write period) required for writing non-video signals different from video signals onto all the pixels before a video signal write period. In the non-video signal write period, the non-video signals are written onto the respective pixels, thereby starting response of the liquid crystal before the start of the video signal write period. In the non-video signal write period, a backlight is turned off, and thereby image degradation is prevented even when the non-video signals are written onto the respective pixels.
