  • Projection device and liquid crystal panel unit for use in the projection device
    Patent number: 7097306
    Abstract: A projection device includes on a chassis a liquid crystal panel for irradiation with light from a light source, a polarizing plate opposing the liquid crystal panel, and an optical compensation sheet provided between the liquid crystal panel and the polarizing plate, for compensating a twist angle of polarized light. The optical compensation sheet is attached to a rotational adjusting mechanism provided on the chassis so that it can be rotatively adjusted within a plane perpendicular to an optical axis L.
