Abstract: A matrix driving method of a liquid crystal display which has liquid crystal which exhibits a cholesteric phase by applying voltages to the liquid crystal through a plurality of row electrodes and a plurality of column electrodes which cross each other at a right angle and face each other. In order to carry out writing on a target pixel which is in a planar state, a voltage V1 is applied to a row electrode which defines the target pixel, and a divided voltage of −V1 is applied to other peripheral row electrodes. Meanwhile, a voltage −V1 is applied to a column electrode which defines the target pixel, and a divided voltage of V1 is applied to other peripheral column electrodes. Thereby, only the target pixel is driven, and the reflectance of the part of the liquid crystal becomes lower. Thus, writing is carried out only on the target pixel.

Abstract: A tapered FOB (20) obtained by forming optical absorbers on the outer surfaces of fibers and bundling these fibers is joined to a slant FOB (10) obtained by bundling fibers, and a CCD (60) is arranged at the output end face of the tapered FOB (20). The slant angle (.beta..sub.0) of a detection surface (11) of the slant FOB (10) on which a fingertip is to be placed is set to an angle at which background light incident from air on the slant FOB (10) is not reflected as total internal reflection at the interface between the core and cladding of the slant FOB (10). The slant angle (.beta..sub.1) of the tapered FOB (20) is set such that background light reaching the tapered FOB (20) becomes incident at the interface between the core and the cladding at an angle smaller than the critical angle at which total internal reflection occurs. Unwanted background light and illumination light are eliminated, and the S/N ratio of a fingerprint image to be detected can be increased.
