Title:
ANTIGLARE FILM, ANTIGLARE FILM MANUFACTURING METHOD, POLARIZING PLATE AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2012/035849
Kind Code:
A1
Abstract:
Disclosed is an antiglare film having improved coated film strength of the anti-glare layer, having film strength (such as excellent scratch resistance and chemical resistance even after weathering tests intended to simulate outdoor use), and having optical characteristics allowing achievement of contrast-rich image quality and reflection prevention of outside light or reflection images. Also disclosed are a manufacturing method of said antiglare film, an excellent polarizing and liquid crystal display device using said antiglare film. The disclosed antiglare film has an antiglare layer on a substrate film. The antiglare layer is aperiodic in the length direction and is arranged irregularly on the substrate film as irregularly shaped protrusions. The arithmetic average roughness Ra of the antiglare layer (JIS B0601: 1994) is 25-300nm, and the haze due to internal scattering of the antiglare layer is 0-1.0%.
