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.
