Liquid crystal display device

A liquid crystal display device comprising:

• a liquid crystal panel including a curved screen;
• a backlight;
• a signal corrector configured to generate a control signal that sets a luminance of the backlight to a lower level at a lower grayscale level of a video signal input thereto, and output the video signal and the control signal;
• a liquid crystal panel driver configured to drive the liquid crystal panel based on the video signal output from the signal corrector;
• and
• a backlight driver configured to drive the backlight based on the control signal output from the signal corrector, wherein
• the liquid crystal panel includes, in order, a first polarizing plate having a first transmission axis, a liquid crystal cell, and a second polarizing plate having a second transmission axis,
• the first transmission axis and the second transmission axis intersect at an angle θ in a plan view of the liquid crystal panel, and
• the angle θ satisfies a relationship of 85°<θ<90° or 90°<θ<95°.
