PROBLEM TO BE SOLVED: To provide a liquid crystal display device which permits the improvement of display quality by writing a voltage at a supply point of an image signal into a pixel. SOLUTION: An image signal supply line VINR is branched, analog switches SWRn-3, SWRn-2, ... are dispersedly connected with the image signal supply line VINRa and image signal supply line VINRb after branching and, thereby, a voltage drop at one image signal supply line VINRa after branching can be prevented from affecting other image signal supply line VINRb etc. Further, the analog switches connected with the different image signal supply lines are allowed to conduct electricity continuously, thereby, for example, a time interval between the conduction timing of the analog switch SWRn-3 connected with the image signal supply line VINRa and the conduction timing of the analog switch SWRn-1 which is allowed to conduct electricity just after the conduction of SWRn-3 is lengthened two times and, after there appears no voltage drop at the image signal supply line VINRa, the analog switch SWRn-1 is allowed to conduct electricity and, as a result, a voltage at a supply point VINR0 of the image signal can be written into the pixel.
