PROBLEM TO BE SOLVED: To enable high voltage drive when a high speed response is required and to make a mounting scale small and to attain cost reduction. SOLUTION: An electrophoretic display apparatus includes a display panel 10 including gate line electrodes 33 and source line electrodes 34 arranged in a matrix to provide a number of pixels at respective intersections of these electrodes, a gate line drive circuit 213 for driving the gate line electrodes 33, and a source line drive circuit 212 for driving the source line electrodes 34. When a display state of the display panel 10 is partially rewritten, a reference voltage of a common electrode 37 is switched to a negative voltage Vcom on the basis of 0 V which is a reference voltage at the time of multi-gradation level display. As a result, the display apparatus can be driven at a higher voltage Vp than the maximum driving voltage Vwmax at the time of multi-gradation level display of the display panel 10.
