摘要： PURPOSE:To satisfy the compability of high nonlinearity and transparency in a visible region by using specific benzophenone or benzophenone deriv. as a nonlinear optical medium. CONSTITUTION:The benzophenone or benzophenone deriv. expressed by the formula is used as the nonlinear optical medium. In the formula, R1 and R2 are both hydrogen or either of R1 and R2 is an electron-donating group and the other is a non-electron-donating group or either of R1 and R2 is an electron- withdrawing group and the other is a non-electron-withdrawing group. The pielectron conjugation system of the benzophenone skeleton is parted by the central carbonyl group and the increase in cutoff wavelength is eventually prevented. Further, such a disposition in which the effect of bending in the carbonyl group as a symmetrical center is hindered so that contribution is made to the development of the high nonlinearity in the crystallized macro state. The material satisfying the high nonlinearity and the transparency in the visible region is thereby obtd.

摘要： PROBLEM TO BE SOLVED: To eliminate light leakage originated from spacer beads in a horizontal electric field mode normally closed type and to improve a contrast ratio by controlling optical leak centering a spacer to become a quadripartite form.
SOLUTION: In this normally closed type liquid crystal display, an active matrix type liquid crystal display device wherein it adopts the horizontal electric field mode and a pre-tilt angle between an alignment control film and liquid crystal is set to 4 degrees or less, optical leak centering a spacer is controlled so as to become a quadripartite form 41. As a method of making the quadripartite formed spacer appear with priority, it is achievable to make liquid crystal molecules on a spacer surface to be aligned almost parallel by making a contact angle between the spacer and the liquid crystal to 60°C or lower. To make the contact angle between the spacer and the liquid crystal to 60°C or lower, to be more specific, a functional group acting as a wetting agent with liquid crystal is recommended to be introduced on the surface of the spacer.

摘要： PROBLEM TO BE SOLVED: To improve the contrast of a lateral electric field type liquid crystal display device in which a birefringent mode is used by providing a film between a spacer and the liquid crystalline materials to form a material which enables to impart liquid crystal aligning performance by polarized-light irradiation by the polarized-light irradiation. SOLUTION: This device has common electrodes 2 and scanning wiring electrode, an insulating film 4', pixel electrodes 3 and signal wirings 10, an insulating film 4, and an organic high polymer film 7 formed on a substrate 1. On the organic high polymer film 7, an alignment control film 8 and spacer beads 40 are arranged and this alignment control film 8 is formed to be interposed partially between the spacer beads 40 and a liquid crystal layer 30. The alignment control film 8 of this constitution is formed of the material which enables to impart the liquid crystal aligning performance by polarized-light irradiation. The liquid crystal aligning performance is given between the spacer beads 40 and liquid crystal layer 30 by the polarized-light irradiation, so that the liquid crystal layer 30 near the spacer beads 40 is free of disordered alignment and aligned in the same direction as the alignment direction of the alignment control film 8. Consequently, a light leak near the spacer beads 40 is reduced to improve the contrast.
