Abstract
There are provided a slit grating and a display device. The passive slit grating according to embodiments of the invention comprises a plurality of grating structures. Each of the grating structures is symmetric about its axial line in a length direction, and an edge in the length direction for each of the grating structures has a non-linear shape. Among adjacent edges of any two of the grating structures that are adjacent, the position of a protrusion at one edge corresponds to the position of a recess at another edge.
