Abstract
Method for producing electrical energy by means of a liquid crystal device having opposite electrode plates between which a liquid crystal is inserted and at least one of which is transparent. The opposite electrode plates include asymmetrical electrodes thereon, at least the electrodes on the transparent plate being transparent. When a voltage is applied across any electrodes of the opposite plates an optical display is provided and when a light is directed to any selected transparent electrodes a voltage is induced between the transparent electrode and the corresponding electrodes on the other plate, to thereby provide a photo-electric converting property which can be used for display, position determination and logic operations etc. When a liquid crystal material which is a mixture of the compounds .rho.-methoxybenzal-.rho.-amino-.alpha.-methyl-cinnamic acid n-propyl-ester, .rho.-methoxybenzal-.rho.-acetoxyaniline, .rho.,.rho.'-di-n-hexyloxyazoxybenzene and anisole is used in the device it can be operated at relatively low temperature.
