Resin liquid-crystal cell substrate, liquid-crystal cells and liquid-crystal display device
First Claim
1. A liquid-crystal cell substrate comprising a resin with a glass transition temperature of not lower than 130°
- C., said liquid crystal cell substrate being shaped into a sheet with a thickness in a range of from 0.1 to 1 mm, and having light output means provided on one of upper and lower surfaces of said sheet so that light incident on a side surface is delivered out of said one of upper and lower surfaces through said light output means;
wherein said light output means comprises prism-like irregularities having steep slopes of 30 to 60 degrees with respect to a reference plane of the sheet.

Abstract
A liquid-crystal cell substrate constituted by a sheet which has a thickness in a range of from 0.1 to 1 mm and is made of a resin with a glass transition temperature of not lower than 130° C. and provided with light output means on one of upper and lower surfaces of the sheet so that light incident on a side surface is delivered out of the one of the upper and lower surfaces through the light output means. Liquid-crystal cells constituted by two cell substrates, and a liquid crystal enclosed in between the two cell substrates, wherein one of the two cell substrates is constituted by a liquid-crystal cell substrate. A liquid-crystal display device constituted by such liquid-crystal cells.
