Abstract

A holographic display panel comprises a plurality of display units, each display unit comprises at least two adjacent pixels, each pixel comprises: a plurality of sub-pixels; and a plurality of phase plates. Diffractive angles of light coming out of the phase plates corresponding to the sub-pixels in a same pixel are the same, a diffractive angle of first light coming out of the phase plates corresponding to a first pixel in one of the display units is different from a diffractive angle of second light coming out of the phase plates corresponding to a second pixel that is different from the first pixel but in the same display unit, and a reverse extension line of the first light and a reverse extension line of the second light intersect at an image plane position.
