This is to provide an image display device using a spacer 103 which can reduce an influence which charge has on an electron orbit greatly without depending on electroconductivity of the spacer 103 itself, and a characteristic of a material by making effectual charge amount zero by controlling positive and negative charge distributions generated on a surface of the spacer 103. This is an image display device using a spacer 103 on a main surface of which concavo-convex structure 106 is formed, the spacer 103 having the concavo-convex structure 106 which can cancel mutually positive charge in a convex portion of the concavo-convex structure 106, and negative charge in a concave portion.
