Abstract: An LCD(Liquid Crystal Display) is provided to improve transmissivity, reduce gray inversion and increase a viewing angle by using a compensation film. An LCD includes an LCD panel, a light source and a compensation film(10). The LCD panel includes a first substrate, a second substrate opposite to the first substrate and a liquid crystal layer(300) interposed between the first substrate and the second substrate. The light source provides light to the LCD panel. The compensation film is formed between the LCD panel and the light source and/or on the face of the LCD panel, which projects light. The optical-path difference of light which passes through the compensation film corresponds to approximately 300 to 320 nm.
