摘要： The present invention, in a display device which includes a SRAM, prevents a phenomenon that power source fluctuation and display timings are not synchronized and hence, flickering occurs on a display surface of a liquid crystal panel. A display device includes a display panel having a plurality of pixels and scanning lines which apply a scanning voltage to the plurality of pixels; and a drive circuit which supplies a scanning voltage to the scanning lines, wherein the drive circuit includes a first booster circuit which generates a first voltage by elevating a reference voltage, a regulator which regulates the first voltage, and a second booster circuit which generates a second voltage by elevating a voltage outputted from the regulator. The second booster circuit generates the second voltage (selective scanning voltage) and a third voltage (non-selective scanning voltage). When video data is inputted from the outside based on an RGB interface, the second booster circuit is operated in response to an external clock.
