Title:
LIGHT REFLECTION FILM HAVING CURVED SURFACE SHAPE AND METHOD FOR MANUFACTURING THE SAME, AND LIGHT CONTROL FILM, OPTICAL FILM, FUNCTIONAL GLASS AND HEAD-UP DISPLAY USING THE LIGHT REFLECTION FILM
Document Type and Number:
Japanese Patent JP2017187685
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a light reflection film with excellent workability and a method for manufacturing thereof in which only the reflectance of specified polarized light can be effectively improved while high visible light transmittance is maintained.SOLUTION: A light reflection film having a curved surface shape includes one or more polarized light reflection layers out of: a polarized light reflection layer PRL-1 which has a planar shape and the central reflection wavelength of 400nm or more and less than 500nm; a polarized light reflection layer PRL-2 which has a planar shape and the central reflection wavelength of 500nm or more and less than 600nm; and a polarized light reflection layer PRL-3 which has a planar shape and the central reflection wavelength of 600nm or more and less than 700nm (any polarized light reflection layer has reflectance to ordinary light at the central reflection wavelength of 5% or more and 25% or less), and in which at least two or more polarized light reflection layers having different central reflection wavelengths from each other are laminated, at least two or more light-reflecting layers to be laminated have characteristics of reflecting polarized lights with the same direction, and have a curved surface shape in an unloaded state and a thickness of 50 μm or more and 500 μm or less.SELECTED DRAWING: Figure 14
