A display device is provided with a shift register having a plurality of bistable circuits, each of the bistable circuits being connected to a corresponding scanning line. An RS flip-flop circuit provided in each of the bistable circuits functions as a memory portion for discriminating a start position of a display region for partial display. When partial display is carried out, first, only the RS flip-flop circuit corresponding to the start position of the display region is put into the set state, that is, only the bistable circuit corresponding to the start position of the display region is put into the set state. Moreover, the scanning lines that are connected to the bistable circuits from the start position to the end position are driven sequentially. During this, only the bistable circuit corresponding to the start position is kept in the set state, and the other bistable circuits are kept in the reset state.
