DEVICE AND METHOD FOR TREATING SUBSTRATE, IMAGE DISPLAY DEVICE AND ITS MANUFACTURING DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method and a device for treating a substrate, capable of manufacturing an image display device having an improved withstand voltage, by removing a corpuscle on the substrate composing the image display device. SOLUTION: A conductor 42 is disposed so as to face the substrate 11 to be treated which is installed in a substrate installation part 34. A voltage is applied between the substrate to be treated and the conductor by a voltage supply part 44 to generate an electric field, and thereby the corpuscle 9 on the substrate to be treated is attracted to the conductor. A dielectric 50 is provided between the conductor and the substrate to be treated, and the corpuscle attracted to the conductor is captured by the dielectric.
