Example embodiments relates to a film having excellent mechanical properties with excellent optical properties such as refractive index, haze, yellow index, and the like, light transmitting laminate, use as a cover film, a multi-layered electronic device, and the like comprising the same. The film comprises an elastic layer, the elastic layer has a refractive index of 1.48 to 1.58, a low temperature damage index is a difference of a tensile modulus and a tensile strength at a certain temperature, and the elastic layer has a low temperature index of 1,300 MPa or less.

Films, light transmitting laminate, cover films and multi-layered electronic devices

A film, a manufacturing method of the film, a cover film, and a multi-layered electronic device include an elastic layer having a storage modulus index Kof 20 to 350 Mpa represented by Equation 1 below and a haze of 3% or less, thereby providing the film having substantially low storage modulus variations over a wide temperature range, with good mechanical properties such as excellent elastic recovery force and good optical properties such as low haze, and provide the cover film or the multi-layered electronic device including the same.
