The present invention relates to a polyester film, an optical film, and a display device including the same. The polyester film has a thickness of approximately 100 to 250 μm, and a difference between a refractive index in a first direction in the surface thereof and a second direction in the surface thereof crossing the second direction is approximately 0.05 or more. Also, the polyester film has a low heat shrinkage rate of 1% or less, so the polyester film may be easily produced into an optical film by applying heat and pressure to a mold for producing lenticular lenses. Accordingly, the optical film has a high difference between a first direction and a second direction in the surface thereof. At the same time, a base layer and lenticular lenses may be integrally formed, so a three-dimensional image may be effectively displayed when the optical film is used for a display device. |
