A display device includes a first substrate, a photosensitive layer, a liquid crystal layer, a second substrate, and a collimation layer that are stacked successively. The photosensitive layer comprises photosensitive units. The second substrate comprises display units and a shutter layer having first holes, any adjacent two of the display units are spaced by the shutter layer, and one of the first holes is located between any adjacent two different ones of the display units. The collimation layer comprises collimators, each of the collimators defines a second hole communicated with a corresponding one of the first holes and facing a corresponding one of the photosensitive units, and a light signal passes through the second hole and the corresponding one of the first holes and reaches the corresponding one photosensitive unit. Reflective-material is arranged on a side of each of the photosensitive units facing the first substrate.
