Abstract
A display capable of excellently writing data when making transition to a standby operation mode is obtained. This display comprises a pixel part having a memory, a power supply circuit formed on the same substrate as the pixel part for operating the memory and a control circuit writing data in the memory after the voltage of the power supply circuit reaches a prescribed value. Thus, the control circuit writing the data in the memory after the voltage of the power supply circuit reaches the set value is so provided that the power supply circuit completely rises and a through current is suppressed in data writing, whereby the data is excellently written in the memory.
