BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a stress imparting film for a display, and a polarizing plate and a display device including the same. Wherein the stress imparting film is a stretched film comprising a polyester resin, wherein the stretching ratio d2 in the second direction with respect to the stretching ratio (d1) in the first direction with respect to the first direction and the second direction perpendicular to each other in a plane, (S1) in the first direction is 1% to 10% at the time of heat treatment at 150 캜 for 30 minutes, and the shrinkage rate (s1) in the first direction is larger than the shrinkage ratio Is 1.2% or more larger than the shrinkage ratio (s2) in the second direction. The stress applying film is attached to the front surface of the display panel and is contracted by a heat treatment process so as to apply stress in the horizontal direction so that a curved display with a certain curvature can be realized and the image distortion such as rainbow stains, Can be prevented. |
