55.1: Invited Paper: A Novel LCD Structure Using Transparent Polymers Free of Birefringence and Scattering Polymers Free of Wavelength Dependency

Abstract

Transparent polymers free of birefringence and scattering polymers free of wavelength dependency are demonstrated. They enable us to improve performance of optical films, pressure sensitive adhesives and backlights. Based on these polymers, we propose a novel LCD structure using a directional backlight and a scattering film.

“…A polarized light emitted from a laser diode, therefore, becomes unpolarized at the lower polarizer when the light impinges onto the LCD panel. To obtain polarized light at the lower polarizer, the light guide plate should have no birefringence [8][9][10].…”

“…The orientation of the chains of the polymer primarily causes the orientational birefringence, whereas elastic deformations cause the photoelastic birefringence. Polymers that display neither [8][9][10]. The polymer in the light guide plate made by injection molding has the orientation of the chains and elastic deformations.…”
