An exemplary liquid crystal display (1) includes a first substrate assembly (11), a second substrate assembly (12) parallel to the first substrate assembly (11), a liquid crystal layer (13) sandwiched between the first substrate assembly and the second substrate assembly, and a discharging circuit (120). The first substrate assembly includes common electrodes (110) formed thereat. The common electrodes are parallel to each other. The second substrate assembly includes scanning lines (1211) that are parallel to each other and that each extends along a first direction, and signal lines (1212) that are parallel to each other and that each extends along a second direction orthogonal to the first direction. The discharging circuit is electrically connected with the common electrodes.
