ABSTRACT:
In the disclosed solid-state diaphragm device, a liquid crystal cell is driven by a matrix driving system. Electrodes of a set on one plate of the cell are arranged in concentric circular relation to each other, while electrodes of another set on the other plate are arranged in radial relation. Related ones of the latter electrodes are connected with one another at their outer or inner peripheral portions to the matrix driving system.
