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.

Abstract: A display device includes a display unit having a display surface on which pixels are arranged in row and column directions. Each pixel includes subpixels having different colors. Subpixels in the pixels include a first subpixel including an electrode having an opening with a longitudinal direction along a first direction and a second subpixel including an electrode having an opening with a longitudinal direction along a second direction. The first and second directions are different from the row and column directions. Subpixels arranged in a third direction are the first or second subpixels. The number of subpixels constituting one color pattern in a fourth direction is 2α. The number of subpixels in which the first and second subpixels arranged in the fourth direction constitute one cycle is 4α. The third direction is one of the row and column directions, and the fourth direction is the other direction.
