ABSTRACT:
An object of the present invention is to provide a memory-type liquid crystal display device capable of controlling a color to be displayed in a peripheral area without using display data based on which display is achieved in the peripheral area. The memory-type liquid crystal display device having a display area and a peripheral area located on the perimeter of the display area, comprising a memory-type liquid crystal provided between first and second substrates and has a first stable state and a second stable state, a first pixel disposed on the display area, a second pixel disposed on the peripheral area and a control unit that applies a reset pulse to a portion of the memory-type liquid crystal corresponding to the first and second pixel so that the portion of the memory-type liquid crystal corresponding to the first and second pixels becomes one of the first and second stable states at a reset period which resets a state of the memory-type liquid crystal, and controls the memory-type liquid crystal so that a portion of the memory-type liquid crystal corresponding to the second pixel maintains its stable state of the reset period at a frame period after the reset period.
