Abstract
An ON/OFF control signal 105 directive of turning ON in a transmissive display mode or turning OFF in a reflective display mode is output by an ON/OFF state controlling means 111 to a light source 115. The ON/OFF control signal 105 is also output to a data signal converting means 104, and the data signal converting means 104 converts a data signal 102 into a data signal 103 in synchronization with the switching of ON and OFF of the light source 115 so as to prevent positive-negative inversion of the display on a liquid crystal panel 114. A data signal potential supplying means 112 supplies a potential of a data signal based on the data signal 103 to a data signal line 113 so as to drive the liquid crystal panel 114.
