ABSTRACT:
With a view to improving the resolution of passively controlled liquid crystal displays, the invention proposes that at least the orientation layer (14.1, 14.2) of one of the two substrate plates (3,4) of the liquid crystal display should be made up of a highly fluorated and preferably perfluorated, aliphatic polymer, which could be, among others, Teflon AF 1600 marketed by the Dupont Company.
An orientation layer formed in accordance with the invention also makes it possible for organic dyestuffs to be used as the chromophore layer, because an orientation layer in accordance with the invention only requires heat treatment temperatures not exceeding 250.degree. C. The pretilt angles obtained by means of the orientation layers in accordance with the invention can be set during the manufacturing process and lie in the range between 25.degree. and about 90.degree..
