<p>A light-reflecting layer (X1), light-reflecting layer (X2), light-reflecting layer (X3), light-reflecting layer (X4) and light-reflecting layer (X5) are each obtained by fixing a cholesteric liquid crystal phase; the light-reflecting layer (X1) and the light-reflecting layer (X2) reflect circularly polarized light in opposite directions, and the center reflection wavelength ?1 of light-reflecting layer (X1) and the center reflection wavelength ?1' of the light-reflecting layer (X2) are effectively equal, with both being within the range of 1190 to 1290nm; the light-reflecting layer (X3) and the light-reflecting layer (X4) reflect circularly-polarized light in opposite directions, and the center reflection wavelength ?2 of the light-reflecting layer (X3) and the center reflection wavelength ?2' of the light-reflecting layer (X4) are effectively equal, and within the range of 1010 to 1070nm; the center reflection wavelength ?3 of light-reflecting layer (X5) is within the range of 850 to 900nm; reflectivity at the wavelength of 790nm does not exceed 15%, and the infrared light reflecting laminate that reflects infrared light can minimize the variation in color of reflected light in a diagonal direction, and has high heat-insulating properties.</p> |
