Abstract
A manufacturing method of a phase retarding film, a manufacturing method of a stereoscopic display apparatus, and a phase retarding film are provided. A light transmissive substrate is provided. An alignment layer is formed on the light-transmissive substrate. The alignment layer is aligned. A birefringent material film is formed on the alignment layer. A reaction-causing light is used to expose a first patterned region of the birefringent material film to induce a reaction on the first patterned region, wherein a second patterned region of the biregringent material film is not exposed to the reaction-causing light. The second patterned region of the biregringent material film is removed.
