Title: Production of polarizing film
Inventor: TANAKA NOBUO
IPC: B29L7/00
Filed: 1993-04-05
Abstract: PURPOSE:To improve polarization performance of a polarizing film obtd. by low temp. and uniaxial. orientation, by uniaxially orienting a film produced by mixing a specified weight ratio of plasticizer to polyvinylalcohol and forming a film from this soln., and uniaxially orienting. CONSTITUTION:This film is obtd. from a soln. containing >=15wt.% plasticizer to polyvinylalcohol (PVA), forming a film, and uniaxially orienting the film. The upper limit of the plasticizer to the PVA is not limited, but preferably <=60wt.% considering the practical strength of the film. If the mixing ratio of the plasticizer is <15wt.%, the effect to improve orienting property of the PVA film is not enough. The stretching rate of the oriented film is >=3 times, preferably >=4 times. If the rate is less than three times, a polarizing film of high polarization property is not obtd. Thereby, the polarization performance of the polarizing film by low temp. orientation can be significantly improved, and the obtd. film has const. transmittance and excellent polarization performance.

Abstract: PURPOSE:To improve contrast ratio by inserting a thin film consisting of an org. or inorg. material in a cell to separate a liquid crystal cell chamber into two layers, upper and lower, using liquid crystal materials including dichromatic dyes of the same color or different colors for these two layers and horizontally orienting the liquid crystals of the two upper and lower layers in different directions. CONSTITUTION:After adhesives 13 such as epoxy adhesive are printed on both of upper and lower glass plates 12 in a frame form, a separator thin film 16 is superposed on one glass plate with application of tension, after which the other glass plate is superposed. Then, the adhesives are set at a high temp. to form an empty cell without contg. liquid crystals, and the cell is hermetically sealed by adhesives through liquid crystal injection holes 17. Incident light 18 is natural light vibrating in all directions. In the nonlighted parts, dichromatic dyes 11 are horizontally oriented in an X-axis direction in the upper layer and therefore the polarized light of the incident light 18 in an X-axis direction is absorbed. Therefore, the remaining polarized light 19 in a Y-axis direction enters the lower layer. In the lower layer, the  dichromatic dyes 11 are horizontally oriented in the Y-axis direction and therefore  the polarized light in the Y-axis direction is absorbed and the incident light 19 is absorbed. In this way, a contrast ratio is improved.
