<P>PROBLEM TO BE SOLVED: To provide a micro lens array sheet capable of improving cover-up characteristics, and to provide a method for manufacturing it. <P>SOLUTION: The micro lens array sheet 1 for backlight includes a substrate 10 which a light is transmitted through, and a plurality of unit lenses 11 arranged on one surface of the substrate 10. In the micro lens array sheet, a concave curved surface 12 which is a curved surface of a concave shape is formed in a gap between the unit lenses 11, and the concave curved surface 12 is formed in non-rotational symmetry to a center axis X along an optical axis of the unit lens 11. <P>COPYRIGHT: (C)2011,JPO&INPIT |
