A display capable of readily driving a memory provided on a pixel part with a power supply circuit in standby operation is obtained. This display comprises the pixel part having the memory and the power supply circuit formed on the same substrate as the pixel part for operating the memory. The power supply circuit at least includes a driver part for amplifying a clock signal and a pump part for performing charge pumping on the basis of the clock signal output from the driver part. Thus, the memory provided on the pixel part can be readily driven with the power supply circuit in the standby operation.
