Abstract
A display device includes: a display panel; a light source configured to emit light toward one surface side of the display panel; a liquid crystal panel interposed between the display panel and the light source and provided to be able to change a transmission degree of light between the display panel and the light source; and a controller configured to control a potential difference between two electrodes facing each other with liquid crystal interposed therebetween. The liquid crystal panel in operation is makes a transmission degree of light tilted toward one side in a longitudinal direction of the display panel in a rectangular shape and a transmission degree of light tilted toward the other side in the longitudinal direction to be different from each other. The potential difference corresponds to an angle of tilt with a smaller transmission degree of light when the liquid crystal panel is in operation.
