Abstract
An upper substrate of a liquid crystal display device includes a color filter and a black matrix. A lower substrate includes a gate insulating layer formed of the substrate, a data line formed on the gate insulating layer, a light shielding pattern formed on the gate insulating layer and spaced apart from the data line, a passivation film formed on the data line and the light shielding pattern, a pixel electrode formed on the passivation film and overlapping a portion of the light shielding pattern. The light shielding pattern includes two light shielding lines formed parallel to and on either side of the data line. Such an arrangement reduces a parasitic capacitance between the pixel electrode and the data line, while maintaining a high aperture ratio.
