The present disclosure relates to an optical laminate or a reddening-resistant layer. The present disclosure can provide an optical laminate that does not cause a so-called reddening phenomenon even when driven or maintained under extremely harsh conditions (e.g., very high temperature conditions), or a reddening-resistant layer applied thereto.

Optical laminate

A device for inspecting a liquid crystal stain of a polarization plate, the device comprising a surface light source; a first polarization member; a polarization plate including a liquid crystal film; a second polarization member; and an inspection source, and a method using the device, the device and the method capable of easily inspecting liquid crystal stains generated on a polarization plate with excellent visibility.

Device and method for inspecting liquid crystal stain of polarizing plate

The present invention relates to a method for manufacturing a polarizer, including: a) immersing and swelling a polyvinyl alcohol-based film in an aqueous solution containing an azo-based dye having an absorption wavelength of 300 nm to 550 nm; b) dyeing the swollen polyvinyl alcohol-based film with an iodine-based dye; and c) stretching the dyed polyvinyl alcohol-based film, and a polarizer manufactured using the method.
