The thickness of a face panel is greater at a peripheral edge portion than
at a center portion. At the inner surface of the face panel, a curvature
radius in a short axis direction on a long axis is set to decrease from
the center of the face panel toward a long axis end and, with L
representing a distance from the center of the face panel to the long axis
end, has a minimal value at a position spaced from the center of the face
panel more toward the long axis end than L/2. A phosphor screen on the
face panel has phosphor layers and non-emitting black layers and a
percentage of the non-emitting black layers per unit area at least in the
neighborhood of a diagonal axis end of the face panel is equal to or
smaller than that at the center portion of the face panel.
