Title:
偏光発光板、及びそれを備えた光学装置
Document Type and Number:
Japanese Patent JP7452969
Kind Code:
B2
Abstract:
To provide a polarized light emission plate capable of providing polarized light with high luminance in an emission wavelength, and a film with optical characteristics different depending on ultraviolet light, visible light, and states of emission/non-emission of them.SOLUTION: In a polarized light emission element which can emit polarized light by absorbing light, wavelengths of the light absorbed by the element and the polarized light differ from each other, and the light polarized within a wavelength range at least of 400 to 700 nm is emitted. A polarized light emission plate includes the polarized light emission element, and a layer capable of reflecting the light within the emission wavelength range of the polarized light emission element.SELECTED DRAWING: None
