摘要：
The present invention relates to A backlight system including an adherend for outgoing light, an optical film subjected to embossing or roughening processing treatment so as to increase the surface area thereof, and a pressure-sensitive adhesive layer containing a pressure-sensitive adhesive polymer having a gel fraction of 35 to 85%, in which the adherend and the optical film are joined through the pressure-sensitive adhesive layer. Further, the invention relates to a process for producing the backlight system, an optical sheet with a pressure-sensitive adhesive which is used in the backlight system, and an image display and an illuminating system using the backlight system.
