Claims

[Scope of utility model registration request]

(1) A liquid crystal is sandwiched between a pair of transparent substrates, and the liquid crystal molecules are twisted homogeneously by 90 degrees between the substrates in the nematic state. A pair of polarizing plates are placed on both sides of the substrates, and the liquid crystal is A liquid crystal panel characterized by using a material that changes from a nematic phase to a smectic phase or from a smectic phase to a nematic phase, and whose light transmittance changes rapidly at a certain temperature.

(2) In the liquid crystal panel, a pair of polarizing plates are arranged so that the planes of polarization are parallel to each other, and at low temperatures the liquid crystal exhibits a smectic phase and high light transmittance, and at high temperatures it exhibits a nematic phase and the optical rotation of the liquid crystal A liquid crystal panel according to claim 1 of the utility model registration claim, characterized in that the light transmittance is reduced by .
