Title: Phase difference film and its production and liquid crystal display device
Inventor: KOZONO YUKO
IPC: G02F1/133
Filed: 1992-07-07
Abstract: PURPOSE:To ameliorate the coloration of background and visual angle characteristic of the liquid crystal display, i.e., the degradation in contrast and change in colors by visual angles by forming the phase difference film of a non-crystal formable polymer having no optically rotation and an optically rotational substance. CONSTITUTION:This phase difference film is formed of the non-crystal formable polymer having no optically rotatory power and the optically rotational substance. The polymer has no optically rotatory power and can exhibit double refractiveness, i.e., has positive or negative intrinsic double refractions. In addition, the polymer has light transmittability. Then, the independent control of the double refractiveness and the optically rotation is possible and the independent changes of the ellipticity and the direction of the ellipse axis of the elliptically polarized light are possible. The optimization thereof is, therefore, facilitated and the return of the intricate elliptically polarized light transmitted through the liquid crystal cell to the linearly polarized light of the unified axis is possible. As a result, the coloration of the background when viewed from the front as well as the degradation in the contrast and the coloration of the background when viewed with a certain angle from the front are ameliorated.

Abstract: PURPOSE:To facilitate forming a fine pattern of 0.5mum or less and improve the radio frequency characteristics and the noise characteristics of, for instance, a GaAs FET or the like by predetermining a higher post-baking temperature by using a conventional aligner and photoresist. CONSTITUTION:After a resist pattern is formed, a GaAs wafer is etched and gate metal 6 such as Al is applied to the etched part and a gate is formed by lift-off. The resist pattern 5 is made of diazide/novolack system positive type photoresist which has a dynamic biscosity of 5.50-6.52 centistoke and is applied by spin-coating. Traditionally, the post-baking is carried out at 90 deg. for 20 minutes. If the temperature is elevated, the photoresist pattern 5 starts deforming and flowing. The flow is progressed uniformly and, by the baking at 130 deg.C for 20 minutes, the edges of the photoresist pattern 5 are advanced by about 0.05mum from the positions immediately after the development and the line width of the pattern is reduced by about 0.1mum totally. After that, the etching is carried out with phosphoric acid system etchant.

Abstract: PURPOSE:To prevent a developer from scattering and falling even if a casing is deformed owing to a temperature rise by making the gap between a developing sleeve and the casing of the developing device wider at the center part than at the vicinity of both plates of the casing. CONSTITUTION:A projection part 11C is provided on the internal wall bottom part of the casing 11 of a developing device main body and the gap l4 of the center part is set as the distance between the tip of the projection and developing roller 13 to a distance wider than the gaps l3 in the vicinity of both side plate parts 11B of the casing 11.
