A backlight and a multiview display employ a light guide having angle-preserving scattering feature and a tapered collimator. The angle-preserving scattering feature is configured to scatter a portion of guided light out of the light guide as emitted light. The tapered collimator is configured to collimate light provided by a light source as collimated light and to communicate the collimated light to the light guide to be guided as the guided light. The collimated light has a collimation factor configured to provide a predetermined angular spread of the guided light, the collimation factor being a function of a taper of the tapered collimator. The multiview display includes multiview pixels that include view pixels as well as the angle-preserving scattering feature that includes a multibeam element having a size that is comparable to a size of a view pixel.

A substrate and a manufacturing method thereof, and a display device are provided. The substrate comprises a base substrate (101), a metal black matrix (111) and an anti-reflection pattern (112A, 112B) for reducing optical reflectivity of the metal black matrix (111), which are arranged on the base substrate (101), and the anti-reflection pattern (112A, 112B) is arranged on a side of the metal black matrix (111) close to a light emission side of the substrate. The anti-reflection pattern (112A, 112B) reduces reflectivity of the metal black matrix (111) on outside ambient light, increases a display contrast of a display device that includes the substrate, and thus improves display quality of the pictures.

A double sided display includes two liquid crystal display panels. When the pixel electrode and the common electrode are in an on state, they form an electric field which causes the liquid crystal molecules to deflect. Due to the effect of a polymer network, the liquid crystal polymer is in a scattering state, which will destroy the condition of total reflection between the two substrates for light from the backlight source. As a result, at least a part of light from the backlight source is emitted from a side of the first substrate after being scattered by the liquid crystal polymer. When the pixel electrode and the common electrode are in the off state, the long axis direction of liquid crystal molecules is consistent with the extension direction of the polymer long chains in the liquid crystal polymer, and the liquid crystal polymer is in a transparent state.
