Title:
WAVELENGTH SELECTIVE ABSORPTION FILTER, ORGANIC ELECTROLUMINESCENCE DISPLAY DEVICE, AND LIQUID CRYSTAL DISPLAY DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/172365
Kind Code:
A1
Abstract:
Provided are: a wavelength selective absorption filter containing a resin and the following dye A and dye D that have principal absorption wavelength bands in different wavelength ranges; and a polarizing plate, organic electroluminescence display device, and liquid crystal display device comprising the same. The absorbances Ab (λ) of said wavelength selective absorption filter at wavelengths λ nm satisfy the relationship represented by the following expression (I). Dye A has a principal absorption wavelength band in wavelengths of 400 to 430 nm in the wavelength selective absorption filter. Dye D has a principal absorption wavelength band in wavelengths of 640 to 730 nm in the wavelength selective absorption filter.
Relational expression (I): 0.05 ≦ Ab(450)/Ab(430) < 1.00
