ABSTRACT:
An electro-optic device comprises a plurality of first electrodes provided on a top substrate and a second electrode provided on a bottom substrate, the first electrodes confronting the second electrode through electro-optical matter which will show electro-optical phenomena by the application of electric field, the first and second electrodes being connected through electrical elements such as resistors or capacitors to a variable voltage source. In this electro-optic device, the electric field applied between the first and second electrodes are partially changed by various means, for instance, by making the areas of the first electrodes different, or by varying the values of the electrical elements such as resistors or capacitors, as a result of which the electro-optical matter shows various electro-optical phenomena.
