Liquid crystal device

摘要

A liquid crystal cell includes a pair of substrates, and a ferroelectric liquid crystal assuming a first and a second orientation state in response to an electric field applied thereto. The liquid crystal cell is combined with an optical detector including a polarizer and an analyzer to form a liquid crystal device. The absorption (or transmission) axes of the polarizer and the analyzer are disposed to intersect each other and are deviated from the optic axis providing the darkest or brightest state of the liquid crystal device.
