Abstract:
Provided are: an image display apparatus in which the utilization efficiency of a virtual image is high and the virtual image having high brightness uniformity can be displayed to be superimposed on a real image; and AR glasses including the image display apparatus. The image display apparatus includes: a display element; one or more cholesteric liquid crystal layers that reflect a display image of the display element; and a transparent reflection element that reflects the image reflected by the cholesteric liquid crystal layer to the cholesteric liquid crystal layer, in which at least one of the cholesteric liquid crystal layers has a structure having a region where a surface pitch changes in a thickness direction.
