Title:
POLARIZING PLATE AND ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/054556
Kind Code:
A1
Abstract:
The present invention provides a polarizing plate and an organic EL display device, wherein even after the organic EL display device obtained by bonding the polarizing plate to an organic EL display panel is exposed to a high-temperature environment for a long time, blackness in a front direction is excellent. This polarizing plate comprises a polarizer formed using a composition containing a first liquid crystal compound and a dichroic material, and an optical anisotropic layer formed using a composition containing a second liquid crystal compound, and disposed adjacent to the polarizer. The content of the dichroic material in the polarizer is 40 mass% or less with respect to the total mass of the polarizer.
