Patent ID: 7199777

Claim:
A liquid crystal display comprising: a liquid crystal panel including a gate line, a data line, and a pixel including a switching element connected to the gate line and the data line; a gate driver applying a gate signal for controlling the switching element to the gate line; and a data driver selecting gray voltages corresponding to gray signals and applying the selected gray voltages to the data line, wherein the gate signal includes a gate-on voltage for turning on the switching element and a gate-off voltage for turning off the switching element, wherein the gate-on voltage has at least two different levels, and wherein at least one of the at least two different levels of the gate-on voltage corresponds to a gray, wherein Von1 + Vconst 2 - Von1 + Vconst 2 × 10 ⁢ % ≤ Von2 ≤ Von1 + Vconst 2 + Von1 + Vconst 2 × 10 ⁢ % , where Von 1 indicates a first level and Von 2 indicates a second level, and Vconst indicates a predetermined voltage level.
