Relaxor ferroelectrics are remarked in non-linear optic applications because an extraordinarily large apparent 'electro-optic Kerr effect' can be observed, even in the so-called paraelectric state. This paper describes the fundamental electro-optic properties of perovskite-type polycrystalline and single crystals, Pb(Zn 1 3Nb 2 3)O3, (Pb, La)(Zr, Ti)O3 and Pb(Mg 1 3Nb 2 3)O3PbTiO 3, firstly. Then, a new type of two-dimensional light valve array for an image projector is introduced. A light shutter array with 10 × 10 pixels was fabricated by a sophisticated tape casting technique. Plate-through and separate electrodes are stacked alternately so as to make vertical addressing by an external electrode connecting separate electrodes and horizontal addressing by a plate-through electrode. The applicative feasibility to a high definition image projector was verified.
