Abstract
The polarizer of the invention is primarily composed of a retardation layer and a light reflecting layer. Since the retardation layer is capable of providing support to the polarizer and correcting color shifting and the light reflecting layer is capable of enhancing brightness and enlarging viewing angle for an LCD employing the polarizer, the polarizer is not only thinner and lighter than a conventional polarizer, but it also have better brightness and viewing angle, and use less power.

A polarizer, comprising:
- a polarizing layer, has a first surface and a second surface opposite to the first surface;
- a support layer, disposed on the first surface of the polarizing layer;
- a retardation layer, disposed on the second surface of the polarizing layer;
- and
- a light reflecting layer, arranged on a surface of the retardation layer opposite to the surface of the retardation layer attaching to the polarizing layer.
