Title:
LONG LIQUID CRYSTAL FILM, LONG POLARIZING PLATE, IMAGE DISPLAY DEVICE, AND METHOD FOR PRODUCING LONG LIQUID CRYSTAL FILM
Document Type and Number:
WIPO Patent Application WO/2019/103143
Kind Code:
A1
Abstract:
The invention relates to a liquid crystal film including a photoalignment layer and provides a liquid crystal film in which phase difference unevenness is suppressed, a long polarizing plate, an image display device, and a method for producing a long liquid crystal film. The long liquid crystal film has, in the order of description, a long base material, an elongated photoalignment layer, and an elongated liquid crystal layer having an in-plane phase difference. When the liquid crystal film is sandwiched between a linear polarizer and an analyzer, placed at the extinction position and irradiated with light, a streaky region where light leakage occurs is present in the elongated liquid crystal layer and the slow axis variation Δβ in the streaky region is larger than 0° and less than 0.04°.
