Display device

A display device capable of presenting a first image to a first user positioned at a first location in front of a display surface and also of presenting a second image to a second user positioned at a second location other than the first location, the display device comprising:

• a display panel including a first display pixel group that contributes to formation of the first image on the display surface and a second display pixel group that contributes to formation of the second image on the display surface;
• a backlight configured to discharge illumination light toward the first display pixel group and the second display pixel group;
• a barrier configured to prevent part of first light produced by wavelength-converting the illumination light with the first display pixel group and part of second light produced by wavelength-converting the illumination light with the second display pixel group from traveling toward the display surface;
• and
• a control unit configured to control the display panel and the backlight, wherein
• the backlight is divided into a plurality of two-dimensional areas,
• the backlight includes a light source in each of the plurality of two-dimensional areas,
• the light sources are independently controllable in each of the plurality of two-dimensional areas of the backlight, and
• the control unit specifies a luminance for each of the plurality of two-dimensional areas of the backlight by controlling the light sources in the backlight in accordance with a display mode of the first image and the second image.
