PROBLEM TO BE SOLVED: To provide a semiconductor display device with high reliability and to provide a semiconductor display device which can reduce power consumption.SOLUTION: A scan line driver circuit is provided with a decoder and is operated such that, in accordance with a signal input to the scan line driver circuit, a pulse is sequentially input only to scan lines included in pixels of lines for which display is performed and a pulse is not input to scan lines included in pixels of other lines for which display is not performed. Then, all pixels or a part of pixels in the line selected by the pulse is supplied with a video signal from a signal line driver circuit, whereby image display is performed only in pixels arranged in a specific area of the pixel part. |
