Abstract: A display device includes a display panel that emits color image light, and a light guiding unit that guides the color image light. When the color image light emitted from the display panel is white image light, color coordinates of the white image light are different from color coordinates of image light obtained as a result of the white image light being guided by the light guiding unit. Specifically, when the display panel emits the color image light by additive color mixing of red, green, and blue, and display unevenness in the display panel is caused by red, in the light guiding unit, the spectral transmittance of cyan, which is a complementary color of red, is adjusted to be smaller than the spectral transmittance of red.

Abstract: A display system includes a display unit that displays pixels with a red sub-pixel, a green sub-pixel, and a blue sub-pixel, and a correction circuit that sets a color temperature for white luminescence. When the pixels perform display in a first tone that is the same tone with the red sub-pixel, green sub-pixel, and blue sub-pixel, the correction circuit sets a first color temperature as a white point. When the pixels perform display in a second tone that is lower than the first tone and that is the same tone with the red sub-pixel, green sub-pixel, and blue sub-pixel, the correction circuit sets a second color temperature different from the first color temperature as the white point.
