Abstract:
1. A 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 having 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 wherein the control unit detects a display color exhibited by an index pixel contained in the display area, and applies the reset pulse to the memory-type liquid crystal so that the portion of the memory-type liquid crystal coinciding with the peripheral area will produce the same display color as the display color exhibited by the index pixel, or the control unit detects a display color exhibited by the largest number of pixels contained in the display area, and applies the reset pulse to the memory-type liquid crystal so that the portion of the memory-type liquid crystal coinciding with the peripheral area will produce the same display color as the display color exhibited by the largest number of pixels.
