Abstract
A light shutter means with a plurality of shutter elements formed of an electro-optical material, the elements being defined independently and three-dimensionally on an upper face of a substantially polyhedral chip and aligned in at least two arrays. Each shutter element has a shutter window for selective light transmission therethrough. A common electrode for the shutter elements extends over opposing faces of the shutter element arrays and to at least one side face of the chip. Each opposing pair of the elements in the one array and in the other array are disposed such that their shutter windows are overlapped with each other as viewed from a direction normal to the direction of element array extension on the chip's upper face.
