Abstract: A see-through display device includes an optical coupler that couples first light input from a first direction and second light input from a second direction that is different from the first direction, the optical coupler transferring coupled light including the first light and the second light to an observer, and a shading member disposed in front of the optical coupler, the shading member transferring the second light to the optical coupler by reducing a light amount of the second light. The see-through display device limits a reflection phenomenon occurring between the optical coupler and the shading member.
