PROBLEM TO BE SOLVED: To provide a display device that further improves an optical performance.SOLUTION: A display device 10 comprises: a video source 11 that projects video light; and a light guide member 20 that guides the video light projected from the video source 11, and reflects the guided video light onto an observer side. The light guide member 20 comprises: a first transparent substrate 21 that is arranged on the observer side; a second transparent substrate 22 that is arrange on a side opposite the observer side of the first transparent substrate 21; an intermediate layer 23 which is arranged between the first transparent substrate 21 and the second transparent substrate 22, and of which a layer thickness is formed almost evenly; and an optical sheet 30 that is arranged between the first transparent substrate 21 and the second transparent substrate 22, and reflects at least a part of the video light projected from the video source 11 onto the observer side.SELECTED DRAWING: Figure 1
