TL;DR: In this paper, a photo alignment layer having excellent long-term stability to light and heat is manufactured by coating a material for the photo-alignment layer, which contains a dichroic dye having two or more polymerizable groups per molecule, on a substrate, and exposing the coating layer to polarized light.
Journal ArticleDOI
Light-Emitting Polyacetylenes: Synthesis and Electrooptical Properties of Poly(1-phenyl-1-alkyne)s Bearing Naphthyl Pendants
TL;DR: In this paper, disubstituted polyacetylenes bearing naphthalene pendants with varying spacer lengths are synthesized, and the effects of structural variations on the optical properties of the polymers are studied.
Journal ArticleDOI
Exact decomposition of a Gaussian-averaged nonlinear function.
TL;DR: The true nonlinear functional dependence of a physical parameter on the local light intensity can be obtained and an exact formula is derived for the decomposition of Gaussian spatially averaged experimental data.

Reflective twisted nematic liquid crystal displays. II. Elimination of retardation film and rear polarizer
TL;DR: Reflective twisted nematic liquid crystal displays consisting of just one input polarizer, a liquid crystal cell, and a rear reflector are discussed in this paper, where all such display modes reported in the literature can be depicted systematically in a series of parameter space diagrams.
