1. An all-around curved polarizer for an all-around curved display device, comprising:
a polarizing layer;
a first protective layer disposed at a side of the polarizing layer facing to the all-around curved display device and having a first coefficient of thermal expansion; and
a second protective layer disposed at the other side of the polarizing layer opposed to the all-around curved display device and having a second coefficient of thermal expansion;
wherein the all-around curved polarizer comprises a flat display area and a curved display area surrounding the flat display area; and
wherein the first coefficient of the thermal expansion of the first protective layer is between 10*10−6/° C. and 20*10−6/° C., and the second coefficient of thermal expansion of the second protective layer is between 25*10/° C. and 40*10−6/ºC.
