Abstract: 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.

Abstract: A neutral polarizer has a dichroic polarizing sheet and a polarizing and scattering sheet laminated on the dichroic polarizing sheet. The polarizing and scattering sheet has anisotropy in light scattering properties depending on a direction of polarization, and has an optical axis showing intense scattering properties. Scattering intensity of linearly polarized light having a polarization direction of the optical axis is greatly dependent on wavelength. An absorption axis of the dichroic polarizing sheet and the optical axis of the polarizing and scattering sheet are in parallel to each other. A liquid crystal display is provided so that this neutral polarizer is disposed on a light source side of a liquid crystal panel.
