Provided is a method of manufacturing a polymer electret. The method of manufacturing a polymer electrets includes forming a polymer thin film, which includes a block copolymer (BCP) having two or more polymer chains covalently bonded together; forming a nano-structure of the BCP in which a first block formed by first polymer chains that self-assemble together and a second block formed by second polymer chains that self-assemble together are micro-phase-separated, by performing an annealing process on the polymer thin film; forming a porous polymer film with a nano-pore by selectively removing one of the first block and the second block; and charging the porous polymer film.

Disclosed is a liquid crystal display capable of improving the bending phenomenon of a liquid crystal panel. The liquid crystal display includes a liquid crystal panel having upper and lower substrates bonded each other with a liquid crystal layer interposed between them; an upper polarization plate attached to the upper surface of the upper substrate; and a lower polarization plate attached to the lower surface of the lower substrate. The upper and lower polarization plates have adhesion layers, respectively, which have different adhesion forces depending on the bending direction of the liquid crystal panel.

Disclosed is a liquid crystal display capable of obtaining a high-quality image without creating flicker and ghost image phenomenon even if Vcom is adjusted, by minimizing variation of refractive index and dielectric constant depending on a temperature through maintaining a liquid crystal layer at a constant temperature. The liquid crystal display comprises a first substrate, a second substrate disposed opposite to the first substrate, an overcoat layer formed on the second substrate, a black matrix layer of a matrix shape formed on the overcoat layer, an ITO layer formed on the black matrix layer, a metal layer formed on the ITO layer, which is formed on the black matrix layer, and a liquid crystal layer interposed between the first substrate and the second substrate.
