Abstract
A video processing circuit includes a boundary detection unit which detects a boundary between a first pixel in which an application voltage which is designated by a video signal Vid-in is lower than a first voltage and a second pixel which exceeds a second voltage in which the application voltage is higher than the first voltage in a normally black mode; and a correction unit which corrects a video signal in which an application voltage to a liquid crystal element corresponding to the first pixel which comes into contact with a boundary detected by the boundary detection unit is designated to be a video signal in which a correction voltage which is higher than the application voltage is designated in a part of period of one frame period, and a correction voltage which is lower than the application voltage is designated in other periods of the one frame period.
