    Abstract: A ferroelectric liquid crystal composition comprises ferroelectric liquid crystal molecules defined by the product between a liquid crystal molecule design parameter, .alpha., and an apparent cone angle, .theta., of the liquid crystal molecules, .alpha..theta., being such that 12.5.ltoreq..alpha..theta..ltoreq.16 wherein .alpha.=(an infrared peak intensity ratio of the alkyl chain portion of a liquid crystal molecule prior to and after switching through an electric field)/(an infrared peak intensity ratio of the core portion of the liquid crystal molecules prior to and after switching through an electric field) and .theta. is an apparent cone angle (.degree.) observed from the direction to the substrate normal and the cone has an imaginary circular cone surface when liquid crystal molecules are rotated along the imaginary circular cone surface at the time of switching through an electric field. The composition ensures high speed response and high contrast.

    Abstract: A small-sized diaphragm device for an image pickup lens system having an electrochromic element the light transmitting properties of which are changed on application of an electrical voltage. The diaphragm device also includes a first set of plural concentrically arranged transparent electrodes, a second set of plural concentrically arranged transparent electrodes and third electrodes formed on the outermost peripheries of these sets of transparent electrodes for acting as counter-electrodes for the transparent electrodes. The diaphragm device has a sufficient light transmittance when in the transparent state, while having high light interrupting properties when in the light interrupting state.
