1. a liquid-crystal apparatus, it is characterised in that possess:

  • Liquid crystal panel, it is between a pair substrate each with alignment films, and clamping includes giving pre-dumping by described alignment filmsThe liquid crystal of the vertical orientating type of the liquid crystal molecule at angle forms, and is modulated light;

    A pair polarization plates, it clamps described liquid crystal panel and configures;

    First phase difference plate, it is configured between the pair of polarization plates, and this first phase difference plate has (i-a) first substrate(ii-a) the first evaporation film, this first evaporation film, keep first refractive index anisotropy, and with first refractive index respectively to differentProperty medium primary optic axis to eliminate by described light produced by described tilt angle characteristic variations first direction tilt sideFormula, is inclined by being deposited with on described first substrate;

    Second phase difference plate, it is configured between the pair of polarization plates, and this second phase difference plate has (i-b) second substrate(ii-b) the second evaporation film, this second evaporation film, keep the second refractive anisotrop, and with the second refractive index respectively to differentProperty medium second optical axis direction eliminate be distinct from described first party by the characteristic variations of described light produced by described tilt angleTo the mode that tilts of second direction, be inclined by being deposited with on described second substrate;

    WithUniaxiality polarizer, it is configured between the pair of polarization plates, keeps the refractive anisotrop of uniaxiality alsoAnd the uniaxiality optical axis through-thickness of the refractive anisotrop medium of uniaxiality;

    Described first phase difference plate can rotate with the normal direction of described first phase difference plate for rotary shaft,Described second phase difference plate can be poor with the normal direction of described second phase difference plate for rotary shaft and described first phasePlate rotates independently,Described first phase difference plate is arranged in the light exit side of described liquid crystal panel, and described second phase difference plate is arranged in describedThe light exit side of one polarizer.
