Abstract:
1. A liquid crystal display device comprising: a first substrate configured to include an active area including a plurality of thin film transistors, a plurality of pixel electrodes, a plurality of gate lines, and a plurality of data lines 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, that includes 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, wherein the second substrate further includes color filter patterns on its portions opposite to only the column spacers within the dummy area, wherein the color filter patterns are not formed on other portion opposite to circuit elements of the driving circuit, wherein a width of the color filter pattern is formed to have a larger width range of about 5% than a width of the column spacer, and wherein a first distance between the thin film transistor array substrate and color filter array substrate within the first region, on which the column spacer is positioned is longer than a second distance between the thin film transistor array substrate and the color filter array substrate in a second region, on which the column spacer is not positioned and the gate driving circuit is formed.
