LIGHT-SELECTIVE REFLECTIVE FILM AND LIGHT-SELECTIVE REFLECTIVE FILM FOR DISPLAYS

摘要

PROBLEM TO BE SOLVED: To provide a light-selective reflective film which is thinner than conventional films but is highly reflective to red light and green light and is transmissive to blue light.;SOLUTION: A light-selective reflective film is provided comprising layers A and layers B alternately laminated to form no less than 11 layers. Each of the layers A is made of an aromatic polyester containing a trimethylene-2,6-naphthalenedicarboxylate unit as a main repeating unit and has a layer thickness in a range of 0.06-0.3 μm, and each of the layer B is made of a polylactic acid composition having a melting point in a range of 150-220°C and has a layer thickness in a range of 0.06-0.3 μm. The film reflects red light and green light and transmits blue light.;COPYRIGHT: (C)2014,JPO&INPIT
