Title:
LIQUID CRYSTAL ALIGNMENT LAYER AND METHOD FOR MANUFACTURING SAME, OPTICAL FILM AND METHOD FOR MANUFACTURING SAME, QUARTER-WAVE PLATE, POLARIZATION PLATE, AND ORGANIC ELECTROLUMINESCENCE DISPLAY PANEL
Document Type and Number:
WIPO Patent Application WO/2019/116989
Kind Code:
A1
Abstract:
Provided is a liquid crystal alignment layer which is formed of a hardened product of an alignment layer composition containing a liquid-crystalline compound capable of exhibiting birefringence of reverse wavelength dispersion and a fluorine atom-containing surfactant, and which includes molecules of the liquid-crystalline compound in a fixed alignment state, wherein at least some of the molecules of the liquid-crystalline compound in the liquid crystal alignment layer are tilted with respect to a layer plane of the liquid crystal alignment layer, the liquid crystal alignment layer has a surface where a ratio MF/T of a surface fluorine atomic weight MF [mol%] measured by X-ray photoelectron spectroscopy with respect to the thickness T [μm] of the liquid crystal alignment layer is between 3.0 and less than 16.0, and the thickness T of the liquid crystal alignment layer is not more than 2.5 μm.
