Title:
HARD-COATED ANTIGLARE FILM, POLARIZING PLATE AND IMAGE DISPLAY DEVICE USING THE SAME, AND METHOD FOR MANUFACTURING HARD-COATED ANTIGLARE FILM
Document Type and Number:
Japanese Patent JP2013178533
Kind Code:
A
Abstract:

To provide a hard-coated antiglare film having superior antiglare properties, capable of highly precisely accommodating thereto even when a haze value is low, and improving depth of black in a black display by preventing white blur from an oblique direction, and to provide a polarizing plate and the like.

The hard-coated antiglare film includes a hard-coating antiglare layer that contains fine particles formed on at least one side of a transparent film substrate. The hard-coated antiglare film has a total haze value Ht within a range of 10-35%. The total haze value Ht and an internal haze value Hin satisfy a relationship of 0.5≤Hin/Ht≤0.9. An asperity-shaped surface of the hard-coating antiglare layer has arithmetic average surface roughness Ra within the range of 0.1-0.3 μm.
