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 substrate, a second substrate, a liquid crystal layer which includes a stripe-like polymer and first liquid crystal molecules having responsiveness to an electric field, a light source and a transparent film which includes second liquid crystal molecules which are not responsive to an electric field. The second liquid crystal molecules have a large inclination angle with respect to the horizontal plane of the transparent film in a first region that is separate from the light source, and have, in a second region positioned between the light source and the first region, a smaller inclination angle than the inclination angle in the first region with respect to the horizontal plane of the transparent film.

Abstract: According to one embodiment, a display device includes a first substrate, a second substrate, a liquid crystal layer, a first light guide element and a light-emitting element. The liquid crystal layer contains stringy polymers and liquid crystal molecules. The first light guide element includes a third transparent substrate including a side surface and a main surface, and a transparent layer disposed on the main surface and having a refractive index lower than that of the third transparent substrate. The light-emitting element opposes the side surface, and the third transparent substrate is adhered to the second transparent substrate while interposing the transparent layer therebetween. The light-emitting element is disposed on the second transparent substrate.

Abstract: According to one embodiment, a display device comprises substrates, a liquid crystal layer containing stringy polymers, a display area with first and second pixels and a light source. In a spatial frequency spectrum obtained by performing FT on a pattern of the polymers which overlap the pixels with respect to first and second frequency components, when an outline in a plane defined by the components in an area having a value of 75% or more of the maximum value is defined as an evaluation circle, and a value obtained by dividing a length of a major axis of the circle by that of a minor axis is defined as an evaluation value, the evaluation value of the first pixel is greater than that of the second pixel.
