Patent ID: 7812918

Claim:
A liquid crystal display device comprising: first and second substrates facing each other; gate lines and data lines formed on the first substrate such that the gate lines and the data lines intersect each other to define pixel regions; thin film transistors formed at respective intersections of the gate lines and the data lines; a black matrix layer formed on the second substrate such that the black matrix layer is disposed corresponding to a region other than the pixel region; color filter layers formed on the second substrate such that the color filter layers are disposed corresponding to the pixel regions, respectively; a liquid crystal layer interposed between the first and second substrates; first column spacers formed on one of the first and second substrates to maintain a cell gap between the first and second substrate wherein each first column spacers has a first height such that the first column spacer is disposed corresponding to one of the gate lines, the data lines and the thin film transistors; wherein each second column spacer has a second height to form a first gap between the second column spacer and the second substrate or the first substrate, respectively, such that the second column spacers are disposed corresponding to the gate line; and third column spacers formed on one of the first substrate and the second substrate wherein each third column spacer has a third height to form a second gap between the third column spacer and the second substrate or the first substrate, respectively, such that the third column spacers are disposed corresponding to the data line, wherein each of the first column spacers has a first area contacting with one of the first substrate and the second substrate, each of the second column spacers has a second area contacting with one of the first substrate and the second substrate, and each of the third column spacers has a third area contacting with one of the first substrate and the second substrate, wherein a sum of the third areas of the third column spacers is larger than a sum of the first areas of the first column spacers and a sum of the second areas of the second column spacers.
