摘要:
A liquid crystal display device is disclosed in which a liquid crystal material mixed with a dichroic dye is held between a pair of substrates whose facing surfaces are provided with electrodes, so that a picture element is made up of a pair of facing portions of the electrodes and a portion of the liquid crystal material sandwiched by the facing portions, in which a reflecting plate is adjacent to one of the substrates, and in which at least one of the substrates is formed of a birefringent material having slow and fast principal axes of birefringence. In the above device, an angle between the direction of the absorption axis of the dichroic dye and one of the principal axes of birefringence of the substrate is selected so that the contrast and viewing-direction characteristic of the device can be improved.

A method for producing an aqueous absorptive polymer-containing resin composition in which a resin composition is doped with an aqueous absorptive polymer includes causing the aqueous absorptive polymer to absorb and be swollen by water beforehand, and milling and microparticulating the water-absorbed and -swollen absorptive polymer at an ultrasonic flow pressure of not less than 50 MPa.
摘要:
A heat-resisting plastic optical fiber which excels in heat resistance and mass production and a manufacturing method thereof. The heat-resisting plastic optical fiber has a core which consists of transparent resin, and clad coated on the outer periphery of the core, which consists of the resin whose refractive index is lower than that of core. Precursor of material for the core material consists of the mixture of a group of monomers which contain polyfunctional monomer and transparent thermoplastic polymer.
