<P>PROBLEM TO BE SOLVED: To provide a sheet for backlight in which handling of the sheet is easy and which demonstrates a high luminance improvement effect. <P>SOLUTION: Lenses 8 are arranged in parallel on one of the faces of a lens sheet 6. An optical sheet 7 arranged on the lens side of the lens sheet 6 and lens crown parts of the lens sheet 6 are pasted together through a reflection layer 10. By this structure, transmittance of light and condensing action to the front face are high and a high luminance improvement effect is demonstrated. Furthermore, since the lens sheet 6 and the optical sheet 7 are pasted together, handling at the time of assembly of the backlight is easy. Furthermore, such a problem that sheets are damaged by mutually rubbing and unevenness of brightness is caused can be solved. <P>COPYRIGHT: (C)2009,JPO&INPIT |
