Abstract:
A spatial light modulator providing an expanded viewing window and a holographic display apparatus including the spatial light modulator are provided. The spatial light modulator includes a mask member having a periodic pattern that is arranged to split an area of each of a plurality of pixels into at least two portions such that a space between lattice spots formed by a period structure of the spatial light modulator increases.
