Title: Phase difference plate and method of continuous production of the same
Inventor: TSUCHIMOTO KAZUYOSHI
IPC: G02F1/13363
Filed: 1999-12-15
Abstract: PROBLEM TO BE SOLVED: To develop a phase difference plate which satisfies specified refractive index characteristics and which is excellent in heat resistance, and to develop a method to stably and efficiently produce that plate. SOLUTION: The phase difference plate consists of a thermoplastic resin film showing positive birefringent characteristics, and the principal refractive indices nx, ny (nx>ny) in the plane and the principal refractive index nz in the thickness direction satisfy the formula (nx-nz)/(nx-ny)0. In the continuous production method of the phase difference plate, while a long-length film made of the thermoplastic resin having positive birefringent characteristics is continuously transported, the film is partly heated, and the dimension of the heated part is changed in one of the width direction and longitudinal direction while the dimension in the other direction is prevented from changing, and also the sucking force is applied in the film thickness direction.  By satisfying the refractive index characteristics expressed by the aforementioned formula which are difficult to obtain in a primarily formed film of a thermoplastic resin, changes in the display characteristics by the viewing angle based on the birefringence of the liquid crystal cell can be highly compensated.
