Abstract: A display device includes a display portion and an opening portion. In the display portion, pixels having different optical characteristics are arranged. The opening portion is arranged so as to face a display surface side of the display portion and causes a light from the display portion to pass in a predetermined direction. With respect to the pixels having the different optical characteristics in the display portion, the pixels having the same color are located in the opening portion.

Abstract: The display device includes an image display panel emitting linearly polarized light from a display area, a retardation plate on the image display panel, a variable phase difference element located on the retardation plate and providing phase difference to an incoming light, and a liquid crystal diffraction element on the variable phase difference element. The variable phase difference element is switchable between an on state, an off state, and an intermediate state, and the phase change of the intermediate state is smaller than the phase change of the on state. A first emission direction of a first emitted light in the on state, a second emission direction of a second emitted light in the off state, and a third emission direction of a third emitted light in the intermediate state are different from each other.
