Abstract

A slit grating and a three-dimensional (3D) display apparatus including the slit grating are disclosed herein, the slit grating includes a plurality of grating structures (11-17) arranged side by side. The widths of the grating structures (11-17) increase and then decrease, along the direction in which the grating structures (11-17) are arranged. A grating structure (13,14) having the largest width may define a trend change point after which the trend in the widths of the grating structure widths changes.
