Abstract: A glass substrate having the first through fourth thin films formed thereon and a glass substrate having the fifth through seventh thin films formed thereon are bonded to each other with the thin-film forming surfaces facing each other through a seal member that is located at the surrounding portion of the substrates. Seal-portion spacers, which are to be mixed in the seal member, are made of glass beads with a spherical particle shape, and the rate thereof to the seal material is set to 7 to 20 Wt %. Further, the particle diameter of the spherical-shaped spacers is represented by (the layer thickness A of a liquid crystal layer)+(the total thickness B+B' of various thin films located within the effective display area)-(the total thickness C+C' of various thin films located in a seal portion)+(0.1 to 0.2 .mu.m).

Abstract: There is provided a plastic liquid crystal display device in which an aligning film processing can be carried out at 150 to 180.degree.

The plastic liquid crystal device comprises a pair of plastic substrates, transparent electrodes, insulating films for protecting the electrodes, aligning films and a liquid crystal, wherein the aligning film is an aligning film which is formed by dissolving a high-temperature sintering organic polymer aligning film made of polyimide or a polyimide-like substance in a solvent, printing a resulting solution thereof on a substrate, removing only the solvent by heating and/or heating under reduced pressure, and sintering the substrate at 200.degree. C. or less.

Abstract: A liquid crystal display device has a liquid crystal layer having super twisted nematic liquid crystal with a twist angle of 260.degree., the liquid crystal layer being sandwiched between a first substrate and a second substrate. A color filter is formed on the second substrate. The first substrate is orientation-processed so that pretilt angles of the liquid crystal to the first substrate are 5.5.degree.. The second substrate is orientation-processed so that pretilt angles of the liquid crystal to the second substrate are 3.0.degree.. Therefore, it is possible to easily reduce occurrence rate of inadequate display and, at the same time, to maintain beneficial characteristics of a liquid crystal display device with a twist angle of 250.degree. or more, i.e., a good temperature characteristic, a small contrast change against a temperature change, and good quality display.
