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.
Claims19
A manufacturing method of a phase retardation film, the manufacturing method comprising:
- providing a light-transmissive substrate;
- forming an alignment layer on the light-transmissive substrate;
- aligning the alignment layer;
- forming a birefringent material film on the alignment layer;
- exposing and inducing a reaction on a first patterned region of the birefringent material film by a reaction-causing light, wherein a second patterned region of the birefringent material film is not exposed by the reaction-causing light;
- and
- etching the second patterned region of the birefringent material film by an etchant, wherein the first patterned region is solidified to a degree that the solidified first patterned region resists the etchant and is not etched by the etchant.
A manufacturing method of a stereoscopic display device, the manufacturing method comprising:
- providing a light-transmissive substrate;
- forming an alignment layer on the light-transmissive substrate;
- aligning the alignment layer;
- forming a birefringent material film on the alignment layer;
- exposing and inducing a reaction on a first patterned region of the birefringent material film by a reaction-causing light, wherein a second patterned region of the birefringent material film is not exposed by the reaction-causing light;
- etching the second patterned region of the birefringent material film by an etchant, wherein the first patterned region is solidified to a degree that the solidified first patterned region resists the etchant and is not etched by the etchant;
- and
- disposing the light-transmissive substrate with the alignment layer and the first patterned region on a display device, wherein an image light emitted from the display device is polarized.
