This invention relates to a transmissive liquid crystal display including a light source (BL), a reflective linearly-polarizing layer (Pr1), a birefringent layer (A) having specific optical properties and specific retardation properties, a light source-side absorptive linearly-polarizing layer (P1), a liquid crystal cell (LC), and a viewer-side linearly-polarizing layer (P2) which are arranged in this order. In the transmissive liquid crystal display of the invention, light leakage is suppressed in oblique directions so that black brightness can be reduced. A reduction in contrast in the normal direction can also be suppressed, which is caused by the distribution of light to the normal direction.

A light pipe is obtained by laminating on one or both surfaces of a light-transmitting resin plate a polarized-light scattering plate having fine birefringent domains dispersed therein and hence showing anisotropy in scattering. The polarized-light scattering plate comprises a transparent film having fine domains dispersed therein comprising a liquid crystal polymer which exhibits nematic at temperatures lower than the glass transition temperature of the polymer constituting matrix of the transparent film and has a glass transition temperature of 50° C. or higher. The light pipe as a laminate may further comprise a specular reflection layer, a polarization-retaining lens and a light diffusion layer laminated thereon. The light pipe may further comprise a light source mounted at least on one side face thereof to provide a planar polarized-light source.

A light diffusing plate is formed of a birefringent film containing dispersed therein minute regions differing from the birefringent film in birefringent characteristics. The minute regions are formed of a thermoplastic liquid-crystal polymer. The difference in refractive index between the birefringent film and the minute regions in a direction perpendicular to the axis direction in which a linearly polarized light has a maximum transmittance, Δn1, is 0.03 or larger and that in said axis direction, Δn2, is not larger than 80% of the Δn1. An optical element is formed of a multilayer structure of the above light diffusing plate and at least either of a polarizing plate and a phase plate. A liquid-crystal display is formed of a liquid-crystal cell and, disposed on one or each side thereof, either the above light diffusing plate or the above optical element.
