摘要:
A video processing circuit for a liquid crystal panel, includes: a boundary detecting unit which detects a boundary between a first pixel whose applied voltage specified by an input video signal is below a first voltage and a second pixel whose applied voltage is equal to or higher than a second voltage which is higher than the first voltage; and a correction unit which corrects, for at least two second pixels one of which is adjacent to the boundary detected by the boundary detecting unit on the opposite side of the first pixel and which are successive in a direction opposite to the boundary, an applied voltage to liquid crystal elements corresponding to the second pixels from the applied voltage specified by the video signal to a voltage which is equal to or higher than the first voltage and below the second voltage.
