Abstract
The present invention relates to an absorptive polarizer and a method for manufacturing the same, and more particularly, to an absorptive polarizer which includes a nano-composite layer in which nanoparticles including a light absorptive element or an oxide or compound thereof are selectively contained in a block copolymer having a first block and a second block which are separately aligned therein, thereby exhibiting excellent durability even when it is exposed under hot and humid environments for a long time, and having polarization degree and transmittance substantially equal to or greater than those of any typical absorptive polarizer manufactured through drawing, as well as a method of easily preparing such an absorptive polarizer as described above at low production costs.
