Abstract
The utility model relates to an improved optically focusing sheet composed of a base plate on which a plurality of parallel fine strips are equipped. Both sides of the ridge of the top end of the fine strip are declinate base faces. A banquette is formed on the declinate base face. The end face of the banquette can be a cambered face form and can be a polygon form. The banquette formed on the declinate base face can be formed on the declinate base face of single side or the declinate base faces of both sides, which can increase the photic area of fine strips. The light ray shot into from the leaded light slice of the aphotic module of the LCD can be made to generate more dioptric light gathering strength through more photic area formed on the optically focusing sheet to enhance light gathering effect of the optically focusing sheet with effect.
