Abstract: A method of driving a dual mode liquid crystal display device includes: applying a first horizontal electric field to the liquid crystal layer for a first duration time during a reset period of a memory mode, the first duration time longer than a frame; eliminating the first horizontal electric field and keeping the liquid crystal layer without the first horizontal electric field for a second duration time during the reset period of the memory mode; applying a first vertical electric field corresponding to a static image for a third duration time during a writing period of the memory mode, the third duration time longer than the frame; and eliminating the first vertical electric field and keeping the liquid crystal layer without the first vertical electric field for a fourth duration time during the writing period of the memory mode.
