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.degree. 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.
