1. A liquid crystal display device, comprising:

  • a substrate;

    a gate line and a gate electrode on the substrate;

    a gate insulating layer on the gate line and the gate electrode;

    an active layer on the gate insulating layer over the gate electrode;

    an ohmic contact layer on the active layer;

    a source electrode, a drain electrode and a data line on the ohmic contact layer, the data line crossing the gate line to define a pixel region;

    a first passivation layer on the source and drain electrodes and the data line;

    a black matrix on the first passivation layer over the active layer;

    a color filter layer on the first passivation layer in the pixel region;

    a second passivation layer on the black matrix and the color filter layer, the second passivation layer exposing the color filter layer in the pixel region; and

    a pixel electrode on the exposed color filter layer in the pixel region, the pixel electrode connected to the drain electrode, wherein the pixel electrode is disposed in a region excluding the second passivation layer such that the pixel electrode does not overlap the second passivation layer.
