Abstract

PURPOSE:To contrive the improvement of workability, productivity, reliability and visibility by constituting each different orientation processing surface by the periodic arrangement of a one-dimensional refining area, so that a two-dimensional diffraction is generated by combining two orientation processing surfaces. CONSTITUTION:On at least one substrate surface in two pieces of substrates 110, 111, the refining areas 140, 150 of an orientation processing having at least two kinds of different liquid crystal orientation functions are arranged so as to have a two-dimensional periodicity as a whole. In this state, a liquid crystal 170 is pinched between two pieces of substrates 110, 111, and by controlling on oriented state of the liquid crystal 170, the optical modulation is executed. In such a way, it is possible to obtain a liquid crystal optical modulator whose workability and productivity are high, in which the steepness of the orientation part against a voltage application is large and which is suitable for time division driving, and has the high visibility with a simple constitution.
