The method of producing an optical film includes the steps of: applying an application liquid containing a liquid crystal material to an alignment substrate; forming a first optical compensation layer on a substrate surface by aligning the liquid crystal material; transferring the first optical compensation layer to a surface of a transparent protective film; laminating a polarizer on the surface of the transparent protective film; and forming a second optical compensation layer on a surface of the first optical compensation layer. The polarizer and the first optical compensation layer are arranged on opposite sides through the transparent protective film. The first optical compensation layer and the second optical compensation layer are formed so that angles formed between respective slow axes and an absorption axis of the polarizer are set within specific ranges.
