ABSTRACT:
An electrooptic shutter array element has a light transmissive substrate, a pair of electrodes having a plurality of opposed terminal portions formed on the substrate, a light shading mask provided with a plurality of windows corresponding to the opposed pairs of terminal portions of the electrodes, and a pair of polarizing plates provided in front and behind the substrate. The terminal portions and windows are properly arranged to distribute an electric field within each of the window areas so that the transmittance of the shutter array element is substantially constant regardless of a temperature change.
