Abstract
A display device includes a transparent display screen, and a first lens group that converges light. The transparent display screen intersects a main optical axis of the first lens group, a distance between the transparent display screen and the first lens group along the main optical axis of the first lens group is less than a focal length of the first lens group, such that, both a display image on the transparent display screen and an environmental image through the transparent display screen and the first lens group or through the first lens group can be observed at an observation position that is located on the main optical axis of the first lens group. Both the observation position and the first lens group are located at a same side of the transparent display screen, and the observation position is farther from the transparent display screen than the first lens group.
