Abstract

A geometric phase optical element and a three-dimensional display apparatus including the same are provided. The geometric phase optical element includes: a liquid crystal layer; a first electrode on a surface of the liquid crystal layer; and a second electrode on another surface of the liquid crystal layer, wherein, when no voltage is applied to the first and second electrodes, the liquid crystal layer is configured such that a phase difference according to an arrangement of the liquid crystal is π and light transmitted through the liquid crystal layer is diffracted by a first deflection angle, and when a first voltage that causes the phase difference according to the arrangement of the liquid crystal to become π/2 is applied to the first and second electrodes, the liquid crystal layer is configured such that the light transmitted through the liquid crystal layer is diffracted by a second deflection angle.
