Abstract:
The display device includes a light source unit that emits light, a first display element, and a second display element. The display device further includes a light separating and synthesizing member that separates the light emitted from the light source unit into first light and second light having different wavelength regions, emits the first light toward the first display element, emits the second light toward the second display element, and synthesizes the first light that has been reflected and modulated by the first display element and the second light that has been reflected and modulated by the second display element. The display device further includes a light absorbing member that covers a part of the first display element. The light absorbing member absorbs a part of the modulated second light reflected by the second display element and directed toward the first display element.
