摘要： A liquid crystal display device of low power consumption is disclosed, which is suitable for use with a portable data processing apparatus, in particular. The liquid crystal display device, comprises: a switch element array substrate (301) having a plurality of data lines (1) and a plurality of scanning lines (2) both arranged being intersected to each other in a matrix form so as to form matrix intersection points; a plurality of pixel electrodes (3) each arranged for each matrix intersection point; and a plurality of first switching elements (6, 7) each arranged for each matrix intersection point and each turned on or off by the scanning line, for applying write voltage supplied from the data line to the pixel electrode, respectively when turned on; a counter substrate (314) having a plurality of counter electrodes (12) each arranged being opposed to each pixel electrode with a gap between the two; a liquid crystal layer (13) sandwiched between the switching element array substrate and the counter substrate; a plurality of memory elements (100) each interposed between the corresponding first switching element and the corresponding pixel electrode, for holding the write voltage supplied through the data line as data, when the first switching element is turned on; a plurality of display control lines (8, 10) each arranged in correspondence to each scanning line; and a plurality of second switching elements (9, 11) each arranged for each matrix intersection point, for controlling connection between the pixel electrode and the display control line on the basis of output of the memory element.
