EDGE LIGHT-TYPE BACKLIGHT REFLECTION FILM AND BACKLIGHT USING SAME

摘要

An object of the present invention is to provide a reflective film for an edge light type backlight that is hardly scratched, and a backlight using the same. The solution is to have a base film and a particle-containing layer containing particles having a particle diameter of 25 to 50 μm and particles having a particle diameter of 1 to 15 μm, and at least one side of the requirements of (i) to (iii) below It is to use a reflective film for an edge light type backlight having a convex portion that satisfies it. (i) There are convex portions with a diameter of 25 to 50 mu m. (ii) the convex portions having a diameter of 25 to 50 μm exist independently without contacting them, and the number of the convex portions having a diameter of 25 to 50 μm is 10 to 100 per 0.64 mm 2 . (iii) The number of convex parts included in the aggregate of convex parts with which the convex parts having a diameter of 25 to 50 µm continuously contact is 10 or less per 0.64 mm 2 .
