Abstract:
A beam expander and a displays including the beam expander are provided. The beam expander includes a holographic optical element (HOE) configured to generate collimated light by diffracting incident light incident thereon from a light source that emits coherent light. The beam expander also includes a diffraction optical element that diffracts light received from the HOE. The light source and the HOE may face each other with the diffraction optical element therebetween. Both the light source and the HOE may be arranged on a side of the diffraction optical element. The light source may be arranged above or below the diffraction optical element.

Claim (Index 4):
The beam expander of  claim 1 , wherein the HOE comprises a hologram layer comprising an interference pattern configured to generate a plane wave that is incident on the diffraction optical element at an acute angle with respect to the diffraction optical element.
