Abstract: PURPOSE: A multilayer optical film is provided to offer the multilayer optical film which has an excellent thermostability with a manufacturing method of the multilayer optical film. CONSTITUTION: A multilayer optical film comprises a structure in which a first resin layer which includes crystalline naphthalenedicarboxylic acid polyester; and a second resin layer which includes polyethylene terephthalate glycol (PETG) are alternately laminated. The manufacturing method of the multilayer optical film comprises: a step of alternately laminating the first resin layer which includes crystalline naphthalenedicarboxylic acid polyester; and the second resin layer which includes polyethylene terephthalate glycol (PETG) after performing a melting extrusion to each resin; a step of heat setting the laminated sheet after extending thereof.
