METHOD FOR DISPOSING FINE OBJECTS, APPARATUS FOR ARRANGING FINE OBJECTS, ILLUMINATING APPARATUS AND DISPLAY APPARATUS

摘要

Provided is a method for disposing fine objects, wherein a substrate (110) is prepared in a substrate preparing step, said substrate having specified positions where fine objects (120) are to be disposed in an area where a first electrode (111) and a second electrode (112) face each other, and in a fluid introducing step, a fluid (121) is introduced on the substrate (110). The fluid (121) contains the plurality of fine objects (120). The fine objects (120) are diode elements, each of which has, as an aligned structure, a front side layer (130) composed of a dielectric material, and a rear side layer (131) composed of a semiconductor. In the fine object disposing step, by applying an alternating voltage to between the first electrode (111) and the second electrode (112), each of the fine objects (120) is disposed by dielectrophoresis with the front side layer (130) facing up at the previously determined position in the area (A) where the first electrode (111) and the second electrode (112) face each other.
