Abstract
A liquid crystal display cell using cell substrates of a flexible organic polymer film and containing liquid crystals injected in a space between the cell substrates. Spacers are dispersed between the cell substrates and immobilized by an orienting layer for orienting liquid crystal molecules. A thin glass substrate can be substituted for the flexible organic polymer film. The liquid crystal display cell is produced by a method including the steps of creating a liquid crystal molecule orienting solution having spacers dispersed therein, applying the orienting film solution containing the spacers to the cell substrates, subjecting the applied solution to a curing treatment, sealing liquid crystals in a space formed between the cell substrates in which the interior thickness corresponds to the diameter of the spacers. The spacers are immobilized by the orienting film during the curing step. The spacers, rather than being mixed in the orienting solution before it is applied, can be scattered on the substrate before the solution is applied or scattered on the solution after it is applied to the substrate.
