Abstract
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.
