Abstract
PURPOSE:To form stripes or dots having random variable pitch in equi-pitch pattern mask on a panel face by bringing the center of the curvature of a panel, the center of the curvature of a mask having smaller radius of curvature and the center of a light source on one line. CONSTITUTION:The center of the curvature O1 of the inner face of a panel 1 is brought to the rear of the center of the curvature O2 of a mask 2 or the radius of the curvature of the mask 2 is made smaller than that of the panel 1, while the center O3 of a light source 1 is located at the center of the curvature O2 of the pattern 2 and the center P0 of the panel, the center Q0 of the mask, the center of the curvature of the panel and the center of the curvature O2 of the mask are brought on single line. The mask 2 has the stripe-shaped (or dot-shaped) light-permeable section with same repeating pitch Consequently stripes or dots having random variable pitch can be formed in equi-pitch pattern mask on a panel face.
