Claim 0:
1. A curved display apparatus, comprising one or more bending portions where the curved display apparatus is bent;
wherein at least the one or more bending portions of the curved display apparatus comprises a stacked structure comprising:
a support layer;
a display panel on the support layer; and
N number of pressure sensitive adhesive layers and M number of flexible base layers between the support layer and the display panel, N is an integer equal to or greater than 3, M is an integer equal to or greater than 2;
wherein the N number of pressure sensitive adhesive layers and the M number of flexible base layers are alternately arranged;
a first one of the N number of pressure sensitive adhesive layers adheres the support layer and a first one of the M number of flexible base layers together;
a last one of the N number of pressure sensitive adhesive layers adheres the display panel and a last one of the M number of flexible base layers together;
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 stacked structure further comprises:
a polarizer on a side of the display panel away from the support layer;
an optical clear adhesive layer on a side of the polarizer away from the display panel; and
a cover on a side of the optical clear adhesive layer away from the polarizer.
