Abstract: A display apparatus is configured to allow a user positioned in a first direction to visually recognize a first image and to allow a user positioned in a second direction different from the first direction to visually recognize a second image. The display apparatus includes a display unit that alternately displays the first and second images; an irradiation unit that provides irradiation light; a color filter that respectively includes first and second areas for the first and second images, through which the irradiation light is transmitted; and a distribution unit that distributes the irradiation light transmitted through the first area of the color filter to the first direction and through the second area of the color filter to the second direction. The color filter includes color components of three primary colors and a white color.

Abstract: According to an aspect, a liquid-crystal display device includes: a liquid crystal layer; and a control unit that controls a display operation. The control unit performs a first display control mode when a response speed of the liquid crystal layer is equal to or higher than a predetermined speed and performs a second display control mode when the response speed of the liquid crystal layer is lower than the predetermined speed. In the first display control mode, the control unit executes a display control at a first frame rate with which a number of frames per unit time is equal to a predetermined number. In the second display control mode, the control unit executes a display control at a second frame rate obtained by dividing the number of frames at the first frame rate by an integer equal to or larger than 2.
