Abstract
An inner surface of an effective portion (,) of a substantially rectangular panel is formed to be a curved surface which satisfies relationships of RyP1<PyP0, RyP1<RyPH, RyP1<½·RyP2 and RyP2<3·RyP1, where RyP0 is a radius of curvature of the inner surface in a short axis direction thereof at the center of the effective portion (,), RyPH is a radius of curvature of the inner surface in the short axis direction at an end of a long axis of the effective portion (,), RyP1 is a radius of curvature of the inner surface in the short axis direction at a position within a range of {fraction (7/16)}·WPH to ¼·WPH from the center of the effective portion in the long axis direction, wherein WMH is a width of the effective surface in a long axis direction thereof, and RyP2 is a radius of curvature of the inner surface in the short axis direction at an end of the effective portion on a line parallel to the short axis passing through the position on the long axis within a range of {fraction (7/16)}·WPH to ¼·WPH from the center of the effective portion.
