Title:
POLARIZING PLATE, DEVICE, HEAD-MOUNTED DISPLAY, ORGANIC ELECTROLUMINESCENCE DISPLAY APPARATUS, AND IMAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2023/214586
Kind Code:
A1
Abstract:
The present invention provides a polarizing plate, a device, a head-mounted display, an organic electroluminescence display apparatus, and an imaging system, the polarizing plate enabling excellent detection performance of an infrared light sensing system when being applied to a device obtained by combining a display element and/or a visible light imaging element and the infrared light sensing system, enabling excellent display performance when the device includes the display element, and enabling excellent imaging performance when the device includes the imaging element. In a polarizing plate according to the present invention, an average transmittance at wavelengths of 400-700 nm is 70% or more, a maximum value of the degree of polarization at wavelengths of 800-1500 nm is 80% or more, and when a wavelength at which the maximum value of the degree of polarization is shown is defined as a wavelength λ1, a transmittance T(λ1) at the wavelength λ1 satisfies a predetermined relationship.
