摘要

Disclosed is a backlight system comprising a light-emitting body to be bonded, an optical film subjected to a roughening process for increasing the surface area, and an adhesive layer containing an adhesive polymer having a gel fraction of 35-85%. In this backlight system, the light-emitting body to be bonded and the optical film are bonded together through the adhesive layer. Also disclosed are a method for producing a backlight system, an optical sheet with adhesive which is used for a backlight system, and an image display and an illuminating device each using a backlight system.
