| abstract | (57) [Summary] [PROBLEMS] To improve the contrast and color purity of a projected image. SOLUTION: A polarization beam splitter 50 for selecting one of P or S polarized light from light emitted from a light source 14 is provided. And a dichroic prism 88 that separates the selected polarized light into red, green, and blue color lights and combines the modulated color lights, and reflection-type liquid crystal devices 80R and 80G that modulate the color-separated color lights. , 80B and the image on the screen 100 In a liquid crystal projector having a projection lens 90 projecting upward, reflection type polarizing plates 88R, 88G, 88B are provided on the back side of the liquid crystal device main body 81. Reflective polarizing plate 80 The degree of polarization of the modulated light emitted from the liquid crystal devices 80R, 80G, 80B is increased by the polarization selection action of R, 80G, 80B, and the contrast and color purity of the projected image are improved. |
