Summary: | In a display device, profile emphasizing is performed without using a frame memory while realizing the further reduction of power consumption. A display device includes a display panel provided with a plurality of pixels each of which has a pixel electrode, and a drive circuit which supplies a video signal to the respective pixels through video lines. Here, the drive circuit includes a profile emphasizing circuit which generates profile emphasizing display data which emphasizes a profile in response to display data inputted from the outside and emphasizes a profile portion of an image to be displayed on the display panel, and a memory which stores the profile emphasizing display data. The profile emphasizing circuit includes a latch circuit which sequentially stores continuous k(k>=2) pieces of display data in display data for 1 display line and an arithmetic circuit which generates the profile emphasizing display data based on the k pieces of display data stored in the latch circuit. |
