摘要： PROBLEM TO BE SOLVED: To provide an apparatus capable of easily detecting parameters such as a pre-tilt angle between a substrate surface and liquid crystal molecule in a liquid crystal panel and a twist angle of liquid crystal molecular allignment in a reflective liquid crystal panel with a simple configuration. SOLUTION: Light from a white light source 1 transmitted through a collimator 2 and an infrared cut filter 3 is defined as monochromatic light (wavelength 1) by a color filter 41, Stokes parameters S1, S21, S31 are measured for the liquid crystal panel 61 held between a polarizing plate (polarizer) 5 and a polarizing plate (polarizer) 8 by using the polarizing plate 8 and a quarter-wave plate 71, Stokes parameters S12, S22, S32 are similarly measured by using the polarizing plate 8 and a quarter-wave plate 72 by using a color filter 42 to transmit light (wavelength 2) with wavelength different from the wavelength 1 next. Then the thickness d of a liquid crystal layer, the twist angle ϕ of the liquid crystal molecular allignment and an average pre-tilt angle θ in the liquid crystal panel 61 are obtained by solving a simultaneous equation of equations (7), (5) and (4).

摘要： PROBLEM TO BE SOLVED: To maintain a required lens characteristic even in a voltage non- impressing state and to control the impressed voltage to a liquid crystal cell to vary the maintained lens characteristic. SOLUTION: In a liquid crystal micro lens where a liquid crystal layer 4 is interposed between two glass substrates 1a and 1b, where hole pattern electrodes 2a and 2b having holes in areas to be lens parts are formed, and glass substrates are so arranged that hole parts of their electrodes face each other, the liquid crystal layer 4 is formed by composite materials of nematic liquid crystal and a monomer. When a prescribed voltage is impressed between hole pattern electrodes, nematic liquid crystal forming the liquid crystal layer 4 has molecules oriented along non-uniform electric fields approximately symmetrical to axes passing the centers of holes and the monomer is hardened by polymerization in this state; and thereby, liquid crystal molecules are kept oriented even when the voltage is not impressed after hardening by polymerization.

摘要： PROBLEM TO BE SOLVED: To obtain an information recording material satisfying both the sensitivity and the stability of information storage by an arrangement wherein a photopolymerization low-molecular liquid crystal material exhibiting smectic phase A is sandwiched by substrates at least one of which is transparent or carried on a substrate. SOLUTION: When an information recording material 2 for optical writing comprising a thin film of photopolymerization low-molecular liquid crystal material in smectic phase A is irradiated linearly with a laser beam from a position controllable laser 1, light is scattered from an irradiated part and the transparency decreases as compared with an unirradiated part. Consequently, writing of a line with laser light can be confirmed. Subsequently, the information recording material 2 for optical writing is irradiated with ultraviolet rays for 10 minutes by lighting in ultraviolet lamp 3 in order to confirm that the writing state of the line with laser light is retained even after polymerization of a photopolymerization low-molecular liquid crystal material.

摘要： PURPOSE: To prevent characteristics, such as focal length, from being changed by temp. and to improve productivity, cost and lightness in weight by consisting the above lens of the photopolymer of a polymerizable liquid crystal compsn. and locally distributing the refractive index in the photocopolymer. CONSTITUTION: This high-polymer lens is produced by depositing, for example, the polymerizable liquid crystal compsn. between two sheets of substrates, such as glass substrates, then impressing locally nonuniform electric fields and magnetic fields on the deposited polymerizable liquid crystal compsn. to the state of locally distributing the orientation of the liquid crystal molecules of the polymerizable liquid crystal compsn. and further, irradiating the compsn. with UV rays or electron beams in this state, thereby immobilizing the orientating state of the liquid crystal molecules into the polymer formed by photopolymn. The high-polymer lens produced in such a manner has the local distribution of the refractive index occurring in the local distribution of the orientation of the liquid crystal molecule skeleton of the polymerization liquid crystal compsn. As a result, the high polymer lens functions as a lens.
