OPTICAL SHEET FOR LIGHT-GUIDE PANEL-TYPE LIQUID CRYSTAL DISPLAY, BACKLIGHT UNIT FOR LIGHT-GUIDE PANEL-TYPE LIQUID CRYSTAL DISPLAY, AND LIGHT-GUIDE PANEL-TYPE LIQUID CRYSTAL DISPLAY

摘要

PROBLEM TO BE SOLVED: To provide an optical sheet for a light-guide panel-type liquid crystal display, having a low refractive index layer with an extremely low refractive index.SOLUTION: This optical sheet A12 for light-guide panel-type liquid crystal display (1000) is obtained by laminating, in the following order, a first optical film (light-guide panel) (1010), a low refractive index layer (20) and a second optical film (reflector plate) (1020), and the low refractive index layer (20) having a refractive index not exceeding 1.25.SELECTED DRAWING: Figure 1
