Document Type and Number:
Japanese Patent JP2018018085
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a white reflective film which is hard to deflect and where luminance unevenness can be improved even when the white reflective film is used while overlapping a case having protrusions and recesses for mounting circuits and the like or used with LEDs, and which is capable of preventing uneven adhesion with a light guide plate and damage to the light guide plate.SOLUTION: A white reflective film for edge-light type backlight satisfies the following conditions (i) to (iii). (i) The white reflective film has rigidity of 3 to 10 mN m. (ii) At least one surface (A) has protrusions formed thereon having the maximum height of the protrusions of 15 to 60 μm. (iii) A side of a surface (B) opposite to the surface (A) has cushion rate of no less than 12%.SELECTED DRAWING: Figure 2
