Abstract

An optical film having a pressure-sensitive adhesive layer on at least one surface thereof, characterized in that the pressure-sensitive adhesive layer has a Tg of -35 DEG C or lower. The above optical film with a pressure-sensitive adhesive exhibits such durability that the curvature thereof can be inhibited even when exposed to a low temperature circumstance lower than room temperature.
