Abstract: According to one embodiment, a display device includes a first transparent substrate, a second transparent substrate, a liquid crystal layer, a third transparent substrate having a first side surface, a second side surface, and an inner surface, a transparent layer arranged on the inner surface, and light emitting elements. The transparent layer includes a band-shaped portion extending from the first side surface toward the second side surface and a frame-shaped portion formed in a frame shape surrounding the band-shaped portion. The band-shaped portion is separated from the frame-shaped portion. A width of the band-shaped portion on a first side surface side is larger than a width of the band-shaped portion on a second side surface side.

Abstract: According to one embodiment, a display device includes a first display panel, and a polarizer opposed to the first display panel and having a transmission axis for transmitting linearly polarized light. The first display panel includes a first substrate, a second substrate opposed to the first substrate, and a first liquid crystal layer held between the first substrate and the second substrate and including streak-like polymers and liquid crystal molecules. An extension direction of the polymers is substantially orthogonal to the transmission axis.
