The non-space region includes a protruding region extending to the light emission region from the non-light emission region, and a conditional expression 0<??2d?tan ? is fulfilled, where ? is a protruding amount (mm) from the non-light emission region of the non-space region, d is a thickness (mm) of the light guide member, and ? is a total reflection critical angle between the light guide member and air.

A display device includes a first transparent display including one or more first transmission areas and one or more first non-transmission areas that include one or more first light emitting elements; and a second transparent display bonded to the first transparent display. The second transparent display includes one or more second transmission areas and one or more second non-transmission areas that include one or more second light emitting elements. The one or more second non-transmission areas include a third non-transmission area. The one or more first non-transmission areas include a fourth non-transmission area overlapping the third non-transmission area. An area of the third non-transmission area is smaller than an area of the fourth non-transmission area. The third non-transmission area is hidden by the fourth non-transmission area when viewing the display device while facing the first transparent display.
