<p>A liquid crystal shuttering device which can be driven with a comparatively low power consumption and is required to use no polarizing element. A liquid crystal cell is so configured that between two or more glass-like substrates (1) made of a substantially transparent material and not oriented or so processed as to be in the state of random irregularity, via spacers (2), a randomly oriented liquid crystal (5) is sealed in the cell, and that electrodes are bonded to the subtrates (1). This device can be utilized light-transmitting or light-reflecting liquid crystal shuttering devices such as a light shield of a welding mask, a shutter for an optical printer and an electronic optical diaphragm.</p> |
