PURPOSE: To decrease the number of driving circuits for scanning electrodes, and to reduce the size of a device and simplify wiring by connecting plural row electrodes of a display element electrically in parallel.
CONSTITUTION: A heat write type display element has a row electrode group and a column electrode group formed on and under a liquid crystal layer which shows thermo-optic effect greatly so that they cross each other nearly at right angles; row electrodes X1WXn are connected in couples, for example, electrically in parallel and applied with signal pulses for liquid crystal heating from scanning electrodes L1WLn. Further, resistances R are connected to odd-numbered row electrodes and reduce currents flowing the odd-numbered row electrodes as compared with those of even-numbered row electrodes, thereby suppressing a temperature rise. Liquid-crystal elements are arranged at intersections of row electrodes X1WXn and column electrodes Y1WYn.
