Abstract
Provided are display devices using electrochromism and PDLC and methods of driving the display devices. A display device may include a plurality of first electrodes and a plurality of second electrodes; a polymer dispersed liquid crystal (PDLC) layer between the first electrodes and the second electrodes; a plurality of third electrodes and a plurality of fourth electrodes; a plurality of electrochromic layers between the third electrodes and the fourth electrodes; and an electrolyte layer between the third electrodes and the fourth electrodes.
