Abstract:
An LCD device is disclosed. The LCD device includes: a first substrate configured to include an active area in which a plurality of thin film transistors, a plurality of pixel electrodes, a plurality of gate lines, and a plurality of data lines are formed for displaying an image, and a dummy area loaded with a driving circuit which is connected to the plurality of gate lines; a second substrate, opposite to the first substrate, configured to include a common electrode together with the plurality of pixel electrodes used for forming electric fields, and color filters and a black matrix formed opposite to the active area; column spacers secured to the first substrate within the active and dummy areas and configured to maintain a constant cell gap between the first and second substrates; and a liquid crystal layer interposed between the first and second substrates. The second substrate is configured to further include color filter patterns formed on its portions opposite to only the column spacers within the dummy area.
