1. An array substrate for a liquid crystal display device, comprising:

  • a plurality of gate lines formed on a first substrate along a transverse direction, each gate line including a gate electrode;

    a first insulating layer formed on the first substrate to cover the gate lines and the gate electrodes;

    a plurality of data lines formed on the first insulating layer along a longitudinal direction, the data lines defining a plurality of pixel regions with the gate lines and each including a source electrode;

    a thin film transistor formed at a crossing region of each of the gate and data lines, each thin film transistor including one of the gate electrodes, a semiconductor layer, one of the source electrodes, and a drain electrode;

    a color filter over the first insulating layer in each pixel region, each color filter having one of red, green or blue colors, the color filters having a plurality of drain contact holes exposing the drain electrodes;

    a light-shielding color filter pattern over each thin film transistor, each light-shielding color filter pattern including red, green and blue color filter patterns, wherein a first color filter pattern of red, green and blue color filter patterns has a trench accommodating a second color filter pattern of the red, green and blue color filter patterns; and

    a pixel electrode over the color filter in each pixel region, each pixel electrode contacting one of the drain electrodes.
