ARRAY TYPE OPTICAL MODULATION ELEMENT, ARRAY TYPE EXPOSURE ELEMENT, PLANE DISPLAY DEVICE, AND METHOD FOR DRIVING ARRAY TYPE OPTICAL MODULATION ELEMENT

摘要

PROBLEM TO BE SOLVED: To increase the speed without using laser light which increases the equipment cost, to increase the degrees of freedom of design of an optical modulation part, and to realize variable contrast control for every picture element even in the case that each optical modulation part is in the binary mode. SOLUTION: With respect to an array type optical modulation element 35 where optical modulation parts 33 having flexible thin films 27 are arranged one-dimensionally or two-dimensionally and flexible thin films 27 are deformed by an electrostatic stress so as to change the transmittance of light passing the flexible thin films 27, each of areas (m) into which one picture element S is divided is provided with the optical modulation part 33.
