Abstract: PURPOSE: An optical unit and a projection type video display device using an optical unit are provided to form an inexpensive optical unit prepared for a reflection type liquid crystal projector and an inexpensive reflection type liquid crystal projector having compact, lightweight and bright characteristics and capable of preventing contrast from being reduced due to leaked light in a black image. CONSTITUTION: In the device, rays from the light source(1) which are polarized perpendicularly to the absorption or reflection axis(99) of the auxiliary polarizer(90) pass through the auxiliary polarizer(90) and reach the reflection polarizing plate(100). Since the reflection axis(99) of the reflection polarizing plate(100) is almost parallel to the absorption or reflection axis of the auxiliary polarizer(90), the rays which have reached the reflection polarizing plate(100) pass through the reflection polarizing plate(100) and reach the reflection liquid crystal panel(110). Generally, when white image signal is received, the reflection liquid crystal panel(110) rotates polarized incident light approx. 90 degrees when reflecting it, so that the polarization direction of the rays reflected by the reflection liquid crystal panel(110) is almost parallel to the reflection axis of the reflection polarizing plate(100). Therefore, the rays reflected by the reflection liquid crystal panel(110) reach the auxiliary analyzer(120) after their optical axis is rotated 90 degrees and reflected by the reflection polarizing plate(100). Since the absorption axis(129) of the auxiliary analyzer(120) is almost perpendicular to the reflection axis of the reflection polarizing plate(100), the rays reflected by the reflection polarizing plate(100) pass through the auxiliary analyzer(120). The rays which have passed through the auxiliary analyzer(120) pass through the projection lens(15) to reach the screen on which a white image is displayed.
