Transflective LCD device having color filters with through holes

1. A transflective liquid crystal display device, comprising:

first and second transparent substrates facing each other with a reflective portion and a transmissive portion;

gate and data lines over the first transparent substrate perpendicularly crossing each other and defining pixel regions;

a thin film transistor connected to the gate and data lines in the pixel region;

an insulator in the thin film transistor on the first substrate covering the gate line;

a passivation layer in the reflection portion on the insulator and on the thin film transistor;

a pixel electrode in the reflective and transmissive portions, wherein the pixel electrode contacts both the passivation layer in the reflective portion and the insulator in the transmissive portion;

a reflector on the pixel electrode in the reflective portion;

color filters on a rear surface of the second transparent substrate, wherein each of the color filters have through holes;

column spacers between the reflector and the color filters, each column spacer corresponding in position to each through hole;

a common electrode under the color filters; and

a liquid crystal layer interposed between the common electrode and the pixel electrode.

2. The device according to claim 1 , wherein the through holes and the column spacers are in the reflective portion.

3. The device according to claim 1 , further comprising an overcoat layer between the color filters and common electrode.

4. The device according to claim 3 , wherein the column spacers and the common electrode are formed on the overcoat layer.

5. The device according to claim 1 , wherein the color filters have red, green and blue colors and the column spacers respectively correspond to the red, green and blue color filters.

6. The device according to claim 1 , wherein the passivation layer has a contact hole exposing a portion of the thin film transistor and the pixel electrode contacts the thin film transistor through the contact hole.

7. The device according to claim 1 , wherein the column spacers includes one of benzocyclobutene (BCB), photo-acrylic resin, cytop and perfluorocyclobutene (PFCB).

8. The device according to claim 1 , wherein the pixel electrode overlaps edge portions of the gate and data lines.

9. The device according to claim 1 , wherein the passivation layer creates a first cell gap in the transmissive portion and a second cell gap in the reflective portion, and the first cell gap is larger than the second cell gap.
