<P>PROBLEM TO BE SOLVED: To provide an ultraviolet optical shutter element for controlling the transmittance of an ultraviolet light by utilizing a liquid crystal. <P>SOLUTION: The ultraviolet optical shutter element is provided with a liquid crystal cell 1 in which electrodes for arranging in a matrix a plurality of polarized light control units for controlling the polarization state of the transmitted light by the application of an electric field to a liquid crystal layer are provided on the facing surfaces of a pair of facing substrates 2 and 3 sandwiching the liquid crystal layer; and a pair of ultraviolet optical polarization plates 13 and 14, disposed so as to sandwich the liquid crystal cell 1, having an absorption axis and a transmission axis perpendicular each other, for absorbing one linearly polarized light component parallel to the absorbance axis, and for transmitting the other linearly polarized light component, among the two orthogonal linearly polarized light components of the incident ultraviolet light. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
