摘要： Phosphor layers (110G, 110B, and 110R) are made of a combination of: blue and green phosphors that are positively charged on their surfaces and baked in an oxygen-nitrogen atmosphere to reduce oxygen vacancy, and that have a β-alumina crystal structure; and a red phosphor made of an yttrium oxide compound. Uniformly forming such phosphor layers on the wall surfaces of barrier ribs (109) provides equal charge characteristics of the phosphors of respective colors, reduces oxygen vacancy in the phosphors, and inhibits adsorption of various gases in the panel production process. This can stabilize the discharge characteristics and prevent luminance degradation at driving the panel.

摘要： A video camera (10) includes a photographing device (16). The photographing device (16) generates an image signal corresponding to an optical image irradiated on a light-receiving surface, and a monitor (34) displays a moving image based on a generated image signal. An amount of incident light into the photographing device (16) is controlled by an aperture apparatus (14) having an aperture blade that moves to a direction perpendicular to a light axis. A moving amount of the aperture blade is restricted by a predetermined value, and this defines a minimum value of an F number. When the moving image is displayed on the monitor (34), it is prohibited to set to the minimum value of the F number.
