Claim 6:
7. A method of fabricating a curved display apparatus, comprising:
providing a display panel;
providing a support layer;
adhering the display panel and the support layer using N number of pressure sensitive adhesive layers and M number of flexible base layers, N is an integer equal to or greater than 3, M is an integer equal to or greater than 2; and
bending an assembly comprising the display panel, the support layer, the N number of pressure sensitive adhesive layers, and the M number of flexible base layers, thereby forming one or more bending portions in the assembly;
wherein adhering the display panel and the support layer comprises:
adhering a first one of the N number of pressure sensitive adhesive layers to a surface of the support layer, thereby adhering the support layer and a first one of the M number of flexible base layers together; and
adhering a display panel to a last one of the N number of pressure sensitive adhesive layers, thereby adhering the display panel and a last one of the M number of flexible base layers together;
wherein at least the one or more bending portions is formed to comprise a stacked structure comprising sequentially the support layer, the N number of pressure sensitive adhesive layers and the M number of flexible base layers, and the display panel;
the N number of pressure sensitive adhesive layers and the M number of flexible base layers are alternately arranged;
a respective one of the N number of pressure sensitive adhesive layers has a thickness in a range of 30 μm to 55 μm;
a respective one of the M number of flexible base layers has a thickness in a range of 20 μm to 40 μm; and
a ratio of the thickness of the respective one of the N number of pressure sensitive adhesive layers to the thickness of the respective one of the M number of flexible base layers is in a range of 0.75 to 2.75;
wherein the method further comprising:
forming a polarizer on a side of the display panel away from the support layer;
forming an optical clear adhesive layer on a side of the polarizer away from the display panel; and
forming a cover on a side of the optical clear adhesive layer away from the polarizer.
