ABSTRACT:
The present invention is to provide a polarizing plate capable of providing a liquid crystal display which is widened in the angle of visibility (in particular, the downward angle of visibility), hardly accompanied by thickening of the thickness of a liquid crystal panel, lowering of contrast due to variation of a visual angle, gradation reverse, black-and-white reverse, and hue variation, by using a light-scattering layer, a polarizer and an optical anisotropic layer comprising a liquid crystal compound, and the polarizing plate of the present invention comprises a polarizer; an optical anisotropic layer containing a liquid crystal compound; and a light-scattering layer containing a light-transmitting resin and a light-transmitting diffusing agent having a refractive index different from that of the light-transmitting resin, wherein the light-transmitting diffusing agent is dispersed in the light-transmitting resin, and liquid crystal display using the same.
