PROBLEM TO BE SOLVED: To prevent data from being erroneously written in a pertinent static memory, to reduce power consumption and to attain the micro-layout of pixels in a display device provided with a holding circuit for holding digital video data in the pixel. SOLUTION: The holding circuit 110 is composed of a first inverter circuit INV1 to which a digital video signal from a drain signal line 61 is inputted and a second inverter circuit INV2 which feeds back the output of the first inverter INV1 positively to the input of the inverter and can be set into a high impedance state at a digital video signal writing time. In this case, the second inverter circuit INV2 is, for example, a clocked inverter.
