Abstract:
A surface emitting device and a display apparatus including the same. The surface emitting device includes: a light source; and a light guide plate having a light exit surface on which holographic patterns are formed, and guiding light emitted by the light source such that the guided light is emitted from the light exit surface, wherein the holographic patterns are arranged so that light incident on the light guide plate without passing through any side surface of the light guide plate can be incident on the holographic patterns at an azimuth greater than 45° at which light emitting efficiency is low and light incident on the light guide plate and reflected by any side surface of the light guide plate can be incident on the holographic patterns at an azimuth at which light emitting efficiency is high.
