<p>A projection-type display device includes an illumination unit, an optical modulation unit, and a projection lens that projects light modulated by the optical modulation unit. The optical modulation unit has a pair of substrates with a liquid crystal layer interposed therebetween, the liquid crystal layer showing negative dielectric anisotropy and an initial alignment thereof having a pretilt in an approximately vertical direction and a predetermined azimuth angle direction, a liquid crystal panel, in which light from the illumination unit is incident on one of the pair of substrates and light is emitted from the other substrate, and a polarizer and an analyzer that are disposed at an incident side and an emission side of the liquid crystal panel, respectively. An optical compensating plate has a liquid crystal layer, in which liquid crystal molecules showing negative refractive index anisotropy having in-plane uniaxial anisotropy are hybrid-aligned, between the liquid crystal panel and the polarizer or between the liquid crystal panel and the analyzer.</p> |
