1. A display device, comprising:
a plurality of display units arranged in an array, wherein each display unit comprises m sub-pixels, the m sub-pixels of the display unit are in one-to-one correspondence with m preset viewing areas, and m is an integer greater than or equal to 2; and
refraction structures in one-to-one correspondence with the plurality of display units, each refraction structure is located on a light emitting side of a display unit corresponding to the refraction structure, and the refraction structure is configured to refract light emitted from each sub-pixel of a corresponding display unit to a viewing area corresponding to the sub-pixel;
wherein each refraction structure is equivalent to a plano-convex lens, and a plane side of the equivalent plano-convex lens is proximal to the display units; and
light emitting surfaces of all sub-pixels of each display unit are located in a focal plane of the plano-convex lens equivalent to the refraction structure corresponding to the display unit.
