Abstract:
1. A liquid crystal display device comprising: a first substrate having a first rubbing direction; a second substrate having a second rubbing direction; a plurality of gate lines and data lines disposed to cross each other on the first substrate to define a pixel region, the gate line having a gate insulating layer having a first permittivity; a thin film transistor at a cross point of the gate lines and the data lines; a storage electrode overlapping a first gate line within the plurality of gate lines; a passivation film on the entire surface of the first substrate including the thin film transistor, the passivation film having a second permittivity; a pixel electrode connected to the thin film transistor and connected to the storage electrode, wherein the pixel electrode has a first end that is spaced a first distance from an end of the storage electrode and that overlaps the first gate line, and wherein the pixel electrode has a second end that partially overlaps a second gate line by an at least one gate line overlap and that partially overlaps a neighboring storage electrode overlapping the second gate line, and wherein the pixel electrode overlaps at least one adjacent data line by an at least one data line overlap, and wherein the pixel electrode on the passivation film corresponds to the pixel region; and a black matrix formed on a predetermined area of the second substrate, wherein the first permittivity, the second permittivity, the at least one gate line overlap, and the at least one data line overlap are selected such that the capacitance of the pixel region is substantially minimized and the aperture ratio of the pixel region is substantially maximized, and the at least one gate line overlap is between about 5 μm and 7 μm.
