The video processing circuit includes a boundary detection unit that detects a specific boundary, which is a part of a boundary of a first pixel for which an applied voltage designated by the video signal is less than a first voltage, and a second pixel for which the applied voltage is more than a second voltage larger than the first voltage, the specific boundary being determined by tilt azimuth of the liquid crystal, and a replacement unit that replaces an applied voltage to a liquid crystal element corresponding to the first pixel with a predetermined voltage from the applied voltage designated by the input video signal when the applied voltage designated by the video signal is less than a third voltage smaller than the first voltage with respect to the first pixel adjacent to the specific boundary.
