Document Type and Number:
Japanese Patent JP6606555
Kind Code:
B2
Abstract:
A laminate includes at least one first reflective layer formed by immobilizing a liquid crystal phase in which a rotational direction of the helical axis is rightward, and at least one second reflective layer formed by immobilizing a liquid crystal phase in which the rotational direction of the helical axis is leftward, in which the laminate has a first transmission band in the wavelength range of 300 to 3,000 nm, the half-width of the first transmission band is 200 nm or less, an average transmittance in a wavelength range from a half-value wavelength A on the short wavelength side of the first transmission band to a half-value wavelength B on the long wavelength side of the first transmission band is 50% or more, and the average transmittance in the wavelength range of 100 nm from the half-value wavelength A to the short wavelength side and the average transmittance in the wavelength range of 100 nm from the half-value wavelength B to the long wavelength side are respectively less than 20%.
