PURPOSE: To easily obtain a lyotropic liquid crystal having excellent developed color and transparency and free from bubble by heating and stirring an isotropic aqueous solution of a linear homopolysaccharide derivative to form a turbid mixture, flocculating and precipitating the solute and removing the phase-separated supernatant.

CONSTITUTION: A linear homopolysaccharide derivative (e.g. hydroxypropyl cellulose) is incorporated with 0.1wt.% aqueous solution of sodium chloride and thoroughly stirred to form a homogeneous isotropic aqueous solution. The aqueous solution is stirred at least once and heated at 80°C to effect the flocculation of the derivative. The obtained turbid mixture is dispersed and left standing for 26hr to effect the flocculation and precipitation of the linear homopolysaccharide derivative. The obtained system is allowed to separate into a turbid flocculated layer and a supernatant layer. After removing the excess supernatant, the system is returned to room temperature to obtain a lyotropic cholesteric liquid crystal. The liquid crystal is sandwiched between substrates and the circumference of the laminate is sealed to obtain a highly transparent liquid crystal laminate exhibiting clear and bright color by dividing a visible light into a reflection light having high saturation and a transmission light having high transparency.
