An all-around curved polarizer for an all-around curved display device comprises a polarizing layer, a first protective layer and a second protective layer. The first protective layer is arranged on a side of the polarizing layer adjacent to the all-around curved display device and has a first coefficient of thermal expansion. The second protective layer is disposed on the other side of the polarizing layer opposite to the all-around curved display device, and has a second coefficient of thermal expansion, and the second coefficient of thermal expansion is greater than the first coefficient of thermal expansion of the first protective layer.
