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 display device includes an image display panel on which pixels each including sub-pixels for displaying a first color, a second color, a third color, and a fourth color are arranged, and a signal processing unit that converts an input value of an input signal for an input HSV color space into an output signal for an extended HSV color space. The signal processing unit divides the extended HSV color space into a plurality of spaces, sets limit proportion values different from each other with respect to at least two spaces of the divided spaces respectively, calculates an extension coefficient α with respect to the input signal by using the input signal and a limit proportion value set with respect to a space according to the input signal, and calculates the output signal based on at least the input signal and the extension coefficient α.
