Abstract

A liquid crystal device, comprising, at least, a pair of polarizing elements being disposed so that the transmission axes thereof are perpendicular to each other; a liquid crystal element disposed between the pair of polarizing elements; and voltage applying means for applying a voltage to the liquid crystal element. The liquid crystal element is such that it enables high-speed optical response, and the optical axis azimuth thereof is rotatable in response to the strength and / or direction of an electric field to be applied thereto. The voltage applying means is capable of controlling a voltage to be applied from the voltage applying means to the liquid crystal element, in response to the liquid crystal molecular alignment in the liquid crystal material. There is provided a liquid crystal device having a temperature-compensating function so as to achieve a good light-dark ratio.

Description

technical field [0001] The present invention relates to a liquid crystal device which can be applied to various display devices such as shutter devices and displays, and can reduce temperature dependence. Background technique [0002] In recent years, with the advancement of technology aimed at the so-called "ubiquitous network society", various demands for speeding up, miniaturizing, and improving quality of the entire display technology have been increasing. In order to meet such needs, in the field of image display and presentation, display image processing technologies such as three-dimensional display, selective non-visualization, and dimming are also rapidly increasing in speed and complexity. On the other hand, the integration of information transmission-related environments including optical communication using fiber optic cables has progressed, and data and information transmission have been increased in capacity and speed. [0003] Generally, in various fields inc...
