Liquid crystal display device

A liquid crystal display device, comprising:

• a color filter substrate having a black matrix, and color filter layers at a designated region determined by the black matrix;
• an array substrate having a gate bus line and a data bus line crossing perpendicularly and defining a unit pixel region, a thin film transistor arranged at an intersection of the gate bus line and the data bus line, a pixel electrode contacting a drain electrode of the thin film transistor and vertically overlapping portions of the gate bus line, the data bus line, an adjacent gate bus line, and an adjacent data bus line, wherein the pixel electrode and the data bus line have an overlapping width in a range of about 0 to 2 micrometers (μm), and the pixel electrode and the adjacent data bus line have an overlapping width in a range of about 3 to 5 micrometers (μm), wherein the pixel electrode and the gate bus line have an overlapping width in a range of about 2 to 4 micrometers (μm), and the pixel electrode and the adjacent gate bus line have an overlapping width in a range of about 4 to 6 micrometers (μm);
• an organic insulating layer on the pixel electrode and the thin film transistor, wherein a surface of the array substrate is rubbed in a 225 degree direction;
• and
• a liquid crystal layer including a liquid crystals between the array substrate and the color filter substrate,
• wherein the liquid crystals at the surface of the color filter substrate are twisted in the 90 degree direction, when applying an electric field is applied thereto, and
• wherein the pixel electrode is not overlapped a source electrode of the thin film transistor.
