- 01 Nov 1993
TL;DR: In this paper, a polarization conversion unit is disclosed, in which a definitely polarized light emitted from a light source is divided into a pair of lights differing in polarized state and are caused to be incident on the optical components including the polarizing beam splitter.

Patent
Liquid crystal device with optical means of high refractive index at pixels and low refractive index between pixels
Junko Shingaki,Shuzo Kaneko,Katsumi Kurematsu,Hideaki Mitsutake +3 more
- 24 Nov 1995
TL;DR: A liquid crystal device is a collection of pixels aligned on a plurality of lines and rows, each of the pixels composed of a pair of electrodes and liquid crystals provided between them as mentioned in this paper.

Patent
Liquid crystal device with two monostable liquid crystal cells
Junko Shingaki,Shuzo Kaneko,Katsumi Kurematsu,Hideaki Mitsutake +3 more
- 02 Aug 1994
TL;DR: In this paper, the conditions for total reflection of incident light were defined for a liquid crystal device, where each of the cells exhibited monostable orientation, and the high-refractive portions and the low-low refractive portions having the refractive indexes the ratio between which satisfies the condition of total reflection.
