<P>PROBLEM TO BE SOLVED: To provide a glare shield sheet restraining the lowering of glare shield characteristic caused by the adhesion of soil and also preventing reflection in display. <P>SOLUTION: In the glare shield sheet, its cross-sectional shape in a perpendicular direction to a sheet surface is rugged shape constituted of a maximal part constituted of a nearly circular-arc shaped curve and a minimal part constituted of a nearly circular-arc shaped curve. In the cross-sectional shape, the average radius of curvature R<SB>1</SB>of the circular-arc curve in the maximal area of the maximal part and the average radius of curvature R<SB>2</SB>of the circular-arc curve in the minimal area of the minimal part satisfy an expression (1): 1≤R<SB>1</SB>/R<SB>2</SB>≤5, and the average radius of curvature R<SB>1</SB>and the average space S<SB>m</SB>between the tops of projecting parts satisfy an expression (2): 4≤R<SB>1</SB>/S<SB>m</SB>≤15. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
