ABSTRACT:
The invention relates to a liquid crystal display element displaying an image using a liquid crystal layer having memory characteristics and a method of driving the element. A liquid crystal display element capable of suppressing the generation of an afterimage attributable to image sticking is provided along with a method of driving the same. The liquid crystal display element includes a display section having memory characteristics including a cholesteric liquid crystal layer and displaying an image when a voltage is applied to the cholesteric liquid crystal layer, the section being capable of keeping the image displayed without electric power, a driving condition storing section for storing a plurality of different driving conditions including a voltage and an application period of the voltage, and a control section determining a display period for which a presently displayed image has been displayed on the display section when the displayed image is rewritten into a new image, acquiring a driving condition according to the display period from the driving condition storing section, and causing the display section to display the new image based on the acquired driving condition.
