A method for manufacturing a polarizer includes: providing a substrate; coating the substrate with a polarizing layer; orienting most of the molecules of the polarizing layer by using a plurality of roller devices; and using a laser device to orient the remaining molecules. The method can increase the shape anisotropy of the polarizer. When the polarizer is used in an LCD (liquid crystal display) device, light provided for a display of the LCD device is increased, and the light utilization rate of the LCD device is improved. The polarizer manufacturing apparatus can further include a transducer between each roller and the substrate having the polarizing layer.
