First Claim
Patent Images
1. A method of preparing a liquid crystal display cell comprising:
- providing a pair of polarizers for sealing a liquid crystal mixture each comprising a layer of polyacetylcellulose bonded by a pair of polyvinylalcohol layers;
forming a pattern transparent electrode having a maximum resistance ratio of about 300 Ω
/cm2 and a thickness of about 800 Å
on each of said polarizers by means of low-temperature sputtering at 5×
10-4 torr and at room temperature;
forming an orientation film on at least one of said polarizers superimposed over said respective pattern electrode;
bonding together said polarizers such that said pattern electrodes are in a facing relationship forming a cavity within said display cell; and
introducing a liquid crystal mixture into said cavity between said pair of polarizers.

2. A liquid crystal display cell consisting of:
-
a pair of polarizers each comprising a layer of polyacetylcelluose bonded by a pair of polyvinylalcohol layers each having formed on one surface thereof by low-temperature sputtering a patterned transparent electrode having a maximum resistance ratio of about 300 Ω
/cm2 and a thickness of about 800 Å
, at least one of said polarizers having superimposed over said transparent pattern electrode an orientation film, said polarizers being bonded together such that said patterned electrodes face each other in a manner so as to form a cavity therebetween; anda liquid crystal mixture present between said transparent electrode bearing surfaces of said polarizers within said cell cavity at least one of said polarizers exhibiting properties of cutting ultraviolet radiation.
