Abstract
An in-plane switching mode active matrix type liquid crystal display device includes a first substrate, a second substrate located opposing the first substrate, and a liquid crystal layer sandwiched between the first and second substrates. The first substrate includes a thin film transistor, a pixel electrode each associated to a pixel to be driven, a common electrode to which a reference voltage is applied, data lines, a scanning line, and common electrode lines. Molecular axes of liquid crystal are rotated in a plane parallel with the first substrate by an electric field substantially parallel with a plane of the first substrate to thereby display certain images. The common electrode is composed of transparent material, and are formed on a layer located closer to the liquid crystal layer than the data lines. The common electrode entirely overlaps the data lines except an area where the data lines are located in the vicinity of the scanning line. The liquid crystal display device further includes a light-impermeable layer in an area where the common electrode entirely overlaps the data lines. The light-impermeable layer is comprised of a black matrix layer having a width smaller t…
