The present invention relates to a display device, and specifically provided is a transmissive glasses display. Aiming at the defects that the existing transmissive glasses display of a reflection waveguide device has low efficiency of light energy utilization and is uncomfortable to wear because of overlarge waveguide thickness, a structure comprising a light guide plate, and an incident reflection device (3) and at least one display reflection device (4, 5, 6) which are arranged in the light guide plate is formed by taking some reflection films having very high reflectivity at the light wave band in which an incident image is located and very low reflectivity at other light wave bands as reflection devices, and is used for conducting total reflection propagation on the incident image between two parallel surfaces (1, 2) inside the light guide plate after the incident image is reflected by the incident reflection device and conducting emergent display on same after the incident image is reflected at the at least one display reflection device. The efficiency of light energy utilization of a glasses display can be improved, the optical performance is stable, and the structure is made compact at the same time, thereby reducing the overall weight of a system. |
