Guest-host liquid crystal element with removable polarizer

摘要

A light control device and an imaging device suitable for the effective and stabilized driving of a Guest-Host type liquid crystal element. A light control device (23) which is provided with a light controlling GH cell (12) and a UV cut filter (65) provided on the light incident side of the GH cell (12), and which is therefore reduced significantly in the quantity of ultraviolet ray applied to the GH cell (12), thereby preventing the photodecompositon or photodegradation of materials constituting a liquid crystal layer in the GH cell (12); and an imaging device such as a CCD camera (50) having this light control device disposed on the optical path thereof.
