Patent ID: 8743299

Claim:
A projection type of display apparatus, comprising: a reflective liquid crystal display device; a polarizing beam splitter; a phase compensator arranged between the reflective liquid crystal display device and the polarizing beam splitter; and an analyzer, wherein the reflective liquid crystal display device comprises a first substrate having a surface on which an optically-transparent electrode is formed, a second substrate having a surface on which pixel electrodes are formed, and a liquid crystal layer composed of nematic liquid crystal having negative dielectric anisotropy and held in a space between the first and second substrates, the liquid crystal being given a pre-tilt angle; wherein the polarizing beam splitter is arranged on the first substrate to be oblique thereto such that the polarizing beam splitter allows only a first polarized light component of incident illuminating light to be transmitted therethrough and to perpendicularly enter the reflective liquid crystal display device and allows only a second polarized light component of reflected modulated light emitted from the reflective liquid crystal device to be reflected therefrom, the first and second polarized light components being polarized oppositely in a polarization direction to each other; the analyzer is configured to remove unnecessary components from the second polarized light component to produce light to be projected from the projector; the nematic liquid crystal includes liquid crystal molecules pre-tilted obliquely to an analyzer side, wherein the pre-tilt provides the molecules with an alignment direction falling into an angle range of 42 to 48 degrees in relation to an oscillation direction of the first polarized light component; and the phase compensator is set to have a retardation of 15 to 20 nm.
