A projection-type display apparatus of the invention aiming at solving the problem of heat generation caused by absorption of light by a polarizing means of a liquid crystal light valve. To overcome this problem, the projection-type display apparatus of the invention includes a light source, a light valve for modulating the light from the light source, and a projection optical means for projecting the light modulated by the light valve, with the light valve including a liquid crystal panel and a polarizing means, provided on the light source side of the liquid crystal panel, and the polarizing means being formed of a multi-layered film which primarily transmits one of two types of polarization axis component light beams and primarily reflects the other of the two types of polarization axis component light beams.
