Abstract: An optical film comprising a silicone elastomer having a support surface and an opposing liner surface; a releasable support contacting at least a portion of the support surface; and a releasable liner contacting at least a portion of the liner surface. The releasable support has a first release tension from the silicone elastomer and the releasable liner has a second release tension from the silicone elastomer, wherein the first release tension and the second release tension are different. In one embodiment, the first release tension is higher than the second release tension, with the first release tension being at least 20% higher than the second release tension. An image display device comprising the optical film is also provided. The optical film provides increase durability, reworkability and workability for improved assembly and manufacturing of image display devices.
