Abstract:
1. A liquid crystal display apparatus, comprising: a light source; a PS convertor; an integrator constituted by two fly-eye lenses and disposed between the light source and the PS convertor; at least one incidence-side polarizer made of an inorganic material; a liquid crystal panel for modulating a polarized state of light output from the incidence-side polarizer to output the modulated light; at least one output-side polarizer made of an inorganic material for outputting the light incident from the liquid crystal panel; a color-composition prism having two ½ wavelength plates directly contacting the color-composition prism on opposite sides, wherein green light transmitted through the polarizer is directly incident on the color composition prism; and a mechanism for turning each of the incidence-side polarizer and the output-side polarizer around an optical axis, wherein the mechanism of turning includes a holder placed in a fixed supporting frame, and the holder has a protrusion being used to turn the holder in the supporting frame, wherein liquid crystals in the liquid crystal panel are aligned in a direction perpendicular to a glass substrate without an applied voltage, and wherein an organic polarizer is included in the liquid crystal display apparatus as an incidence-side polarizer or an output-side polarizer.
