Transflective LCD device and fabrication method thereof

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 the gate and data lines near in the pixel region;
• an insulator in the thin film transistor on the first substrate with covering the gate line;
• a passivation layer in the reflective 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 potion and the insulator in the transmissive portion;
• a reflector on the pixel electrode within the reflective portion;
• red, green and blue color filters on a rear surface of the second transparent substrate, the red, green and blue color filters corresponding to pixel regions, wherein some of the red, green and blue color filters have through holes and some do not have through holes;
• column spacers between the reflector and the color filters, each column spacer corresponding in position to a color filter that does not have a through hole;
• a common electrode under the color filters;
• and
• a liquid crystal layer interposed between the common electrode and the pixel electrode.

A method of forming a color filter substrate for use in a transflective liquid crystal display device, comprising:

• forming a color resin on a transparent substrate having reflective and transmissive potions;
• disposing a mask over the color resin;
• irradiating light to the color resin through the mask;
• forming color filters having through holes;
• forming an overcoat layer over the transparent substrate to cover the color filters;
• forming column spacers on the overcoat layer, wherein each column spacer corresponds in position to the through hole;
• and
• forming a transparent pixel electrode on the overcoat layer exposed between the column spacers.
