[0014] The three tubular accommodating cavities 302r, the tubular accommodating cavities 302b, and the tubular accommodating cavities 302g constitute a pixel unit 308. In the halogen unit 308, the arrangement of the tubular accommodation cavity 302r, the tubular accommodation cavity 302b, and the tubular accommodation cavity 302g is not limited, for example, in FIG. The right is a tubular accommodating cavity 302r, a tubular accommodating cavity 302g and a tubular accommodating cavity 302b, and in the pixel unit 308 in the lower right corner, from left to right, the tubular accommodating cavity 302b, the tubular accommodating cavity 302r and the tubular volume The chamber 302g is placed. Ο When a voltage difference is applied between the transparent electrode 42 and the pixel electrode 22, the charged particles 306 in the tubular accommodating chamber 302 approach the transparent electrode 42. Taking a pixel unit 308 as an example, a voltage difference VI, V2, and a difference are respectively applied between the pixel electrode 22 and the transparent electrode 42 corresponding to the tubular accommodation cavity 302r, the tubular accommodation cavity 3, 02b, and the tubular accommodation cavity 302g.
