PROBLEM TO BE SOLVED: To suppress decrease in display quality due to influences of a transverse electric field. SOLUTION: A liquid crystal panel 100 includes a liquid crystal element having a liquid crystal 105 interposed between a pixel electrode 118 provided on an element substrate 100a and a common electrode 108 provided on a counter substrate 100b. A video processing circuit 30 detects a risk boundary, which is a part of the boundary between a dark pixel where an applied voltage to the liquid crystal element corresponding to a gradation level designated by a video signal Vid-in is lower than a threshold voltage Vth1 and a bright pixel where an applied voltage is equal to or higher than a threshold Vth2, and which is determined by a tilt azimuth of liquid crystal molecules; and when the applied voltage to the dark pixel in contact with the detected risk boundary is less than a voltage Vc, the video processing circuit 30 replaces the voltage applied to the dark pixel, from the applied voltage corresponding to the gradation level designated by the video signal, to the voltage Vc.
