Abstract

A liquid-crystal display device and a driving method thereof are disclosed. The liquid crystal display device comprises: a target level generator (105) configured to output target level data during every horizontal period based on analyzed data of an input image; and a multi-step common voltage generator (120) configured to output a target voltage corresponding to the target level data and a reference level voltage corresponding to preset reference data within one horizontal period (1H) and output a common voltage (Vcom), wherein the common voltage (Vcom) is generated as first and second target voltages within first and second horizontal periods, respectively, wherein the reference level voltage is generated for a 1/2 horizontal period (1/2 H) or less, between the first and second target voltages, and is lower than the first target voltage and higher than the second target voltage.
