Display Apparatus

Abstract

The present disclosure provides a display apparatus. The display apparatus includes a light source; a compensating diffraction optical element which reflects a light incident from the light source; and an off-axis reflection diffraction optical element which reflects a light reflected from the compensating diffraction optical element to the outside, wherein the compensating diffraction optical element reflects the light incident from the light source toward the off-axis reflection diffraction optical element while adjusting the reflection angle of the light incident from the light source so as to compensate for the reflection angle distortion of the light reflected from the off-axis reflection diffraction optical element.
