To maintain image quality when a field frequency is dynamically changed. In an image display area AA, control lines 4a are arranged respectively corresponding to scanning lines 3a, and TFTs 50 and 51, a pixel electrode 9a, and a storage capacitor 52 are arranged at each intersection of one of data lines 6a and scanning lines 3a. A control signal SC supplied through the control line 4a controls the TFT 51 for an on and off operation. A timing signal generator circuit 300 activates the control signal SC when a field frequency is not higher than 60 Hz, and deactivates the control signal SC when a field frequency is above 60 Hz. In this way, whether or not to connect the storage capacitor 52 to the pixel electrode 9a is determined.
