Abstract
A liquid crystal display (LCD) panel comprises a first substrate; a first electrode layer; a colour filter film comprising red, blue and green filter layers; a second substrate; a liquid crystal layer; and a second electrode layer. The first electrode layer is disposed on the first substrate and the colour filter film is disposed on the first electrode layer, and the liquid crystal layer is disposed between the colour filter film and the second substrate. According to the present invention, colour filter film with a high dielectric constant (i.e. larger than 3) is employ to effectively increase voltage of the liquid crystal layer to effectively promote the contrast of images displayed by the LCD panel.
