Abstract
The invention provides a retardation film, a method for producing the same and a display apparatus comprising the same. The retardation film comprises a phase retardation layer and a cured material layer formed by curing a curable material applied on the phase retardation layer, wherein the cured material layer is disposed on the light-emitting side of the phase retardation layer. In the retardation film of this invention, since the cured material layer is formed by curing the curable material applied on the phase retardation layer, the laminating equipment can be omitted and the equipment investment can thus be decreased, thereby lowering the production cost.
Claims14
A retardation film, comprising a phase retardation layer and a cured material layer formed by curing a curable material, wherein the phase retardation layer comprises an alignment layer and a liquid crystal layer disposed on the alignment layer, and the cured material layer is disposed on the liquid crystal layer opposite to the alignment layer and has a thickness in a range of 20 μm to 500 μm.
A display apparatus, comprising a display device and a retardation film disposed on the light-emitting side of the display device, wherein the retardation film comprises a phase retardation layer and a cured material layer formed by curing a curable material, wherein the phase retardation layer comprises an alignment layer and a liquid crystal layer disposed on the alignment layer, and the cured material layer is disposed on the liquid crystal layer opposite to the alignment layer and has a thickness in a range of 20 μm to 500 μm.
A method for producing a retardation film, comprising:
- forming a phase retardation layer comprising an alignment layer and a liquid crystal layer disposed on the alignment layer;
- applying a curable material on the liquid crystal layer opposite to the alignment layer;
- and
- forming a cured material layer by curing the curable material using a curing process, wherein the cured material layer has a thickness in a range of 20 μm to 500 μm.
