Abstract

An augmented reality display device and a pair of augmented reality glasses are provided. The augmented reality display device includes a substrate, an imaging element and a first optical element. The substrate includes a first side and a second side opposite to each other. The imaging element is configured to display a primary virtual image formed by virtual image light. The first optical element is configured to receive the virtual image light, orient the virtual image light to magnify the primary virtual image into a secondary virtual image, and make the virtual image light exit from the first optical element in a direction from the second side to the first side.
