A liquid crystal display device includes: first and second substrates facing and spaced apart from each other; a gate line and a data line on the first substrate, the gate line and the data line crossing each other to define a pixel region; a thin film transistor and a pixel electrode in the pixel region on the first substrate, the thin film transistor connected to the gate line and the data line, the pixel electrode connected to the thin film transistor; a common electrode on the second substrate, the common electrode facing the pixel electrode; at least one first reset electrode and at least one second reset electrode on one of the first and second substrates, the at least one first reset electrode and the at least one second reset electrode spaced apart from each other; and a bi-stable chiral splay nematic liquid crystal layer between the first and second substrates, the bi-stable chiral splay nematic liquid crystal layer having bi-stable states of a splay state as an initial state and a π-twist state, wherein first and second reset voltages are applied to the at least one first reset electrode and the at least one second reset electrode, respectively, and wherein the bi-stable chiral splay nematic liquid crystal layer transitions from the π-twist state to the splay state by applying the first and second reset voltages.
