Abstract
The present disclosure provides a display device and a manufacturing method thereof, in the field of display technology. The display device can comprise: a display panel and a light ray control component disposed on a light emergent side of the display panel, wherein the light ray control component comprises a plurality of zone plates; each sub-pixel region on the display panel corresponds to one of the zone plates, and the zone plate corresponding to any sub-pixel region is used to control a direction of light rays emitted from the any sub-pixel region. In the present disclosure, the light ray control component comprising a plurality of zone plates is disposed on the light emergent side of the display panel, and each sub-pixel region of the display panel corresponds to one zone plate. Therefore, the problem in the related art that the light rays emergent from the light emergent side of the display panel are divergent light, and a direction of the light rays is hard to control is solved. The effect of controlling the direction of the light rays emergent from the light emergent side of the display panel by the light ray control component is achieved.
