Liquid crystal panel and projection display with use of liquid crystal panel

摘要: In an optical system phase device such as λ/2 plate or a λ/4 is used to convert S polarization P and vice versa. the projection display, white light emitted from source separated by color separation system, including dichroic mirrors prism, into three primary colors which are modulated modulation elements. Then, lights synthesized synthesis projected element onto screen. When appropriate plates inserted appropriately in of conversion between occurs bandwidth becomes narrow, purity can be improved. A thick transparent preferably adhered element. absorption film applied ineffective plane plate. The like improve contrast. invention liquid crystal panels crystal/resin display panels, beam writing type panel micro mirror panel. Preferably, set rotatable so adjust contrast appropriately.
