Abstract:
Disclosed is a polyester film for optical applications, and more specifically to a polyester film having refractive index of 1.6 to 1.7 and a film having refractive index of 1.4 to 1.6 on both surfaces of the polyester film, wherein a thickness of each coating layer is 0.03 to 0.1 μm and total light transmittance of the entire film is 93% or more. The polyester film according to the embodiment has total light transmittance higher than the polyester film without the coating layer and is more suitable to use the polyester film for optical applications due to the excellent adhesive strength between the polyester film and layer for the post-processing working.
