ABSTRACT:
A liquid crystal display is provided, which includes: 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. 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. The gray voltages include pairs of positive and negative voltages (V+, V−) andV++V-2=Vconstfor each gray, where Vconst indicates a predetermined level. The gate-on voltage continuously decreases from a first level to a second level for a predetermined time, and the first level (Von1) and the second level (Von2) satisfy a relation given by,Von⁢⁢1+Vconst2-Von⁢⁢1+Vconst2×10⁢%≤Von⁢⁢2≤Von⁢⁢1+Vconst2+Von⁢⁢1+Vconst2×10⁢%.
