<p>To drive a transflective liquid-crystal panel in such a manner as to increase a contrast ratio during a transmissive-type display time while appropriately maintaining the brightness during a reflective-type display; provided are a Y driver circuit (100) and an X driver circuit (110) for supplying an applied voltage having an effective value of a magnitude corresponding to the gray scale level indicated by gray scale data to a liquid crystal element(10), and a driver control circuit (310) for switching the setting of each magnitude of an effective value of an applied voltage with respect to each gray scale level in the X driver circuit to a setting for a reflective-type display in response to the non-switching on of a light source (212) and to a setting for a transmissive-type display in response to the switching on of the light source. <IMAGE></p> |
