PURPOSE:To improve the response properties under applied votage as well as the transmittance by forming electrodes each consisting of an electrically conductive transparent film and an electrically conductive film having a lower resistance value and a smller width than the transparent film on both sides of an element having an electrooptic effect. CONSTITUTION:Electrodes 14 each consisting of an electrically conductive transparent film 12 of In2O3-SnO2 as the 1st layer and a metallic film 13 of Al, Cr-Au or the like on the 1st layer are formed on both sides of a PLZT element 11 having an electrooptic effect. The film 13 is an electrically conductive film having a lower resistance value than the film 12, and the width W2 of the film 13 is made smaller than the width W1 of the film 12. The CR time constant determined by the capacitance of PLZT present between the films 12 and the resistance value of the films 12 is reduced, so the work time required to open the shutter can be shortened. |
