| description | A pixel circuit includes a first switching transistor between a gate and a drain of a driving transistor, a second switching transistor, and an auxiliary capacitor connected to the second switching transistor. The second switching transistor transfers a data signal voltage from a data line to a storage capacitor through the driving transistor and the first switching transistor. The auxiliary capacitor retains the auxiliary charges depending on the data signal voltage from the data line during a first period where the second and first switching transistors are ON. The auxiliary charges are transfer from the auxiliary capacitor to the storage capacitor through the first switching transistor and the driving transistor during the second period where the second switching transistor is OFF and the first switching transistor is ON. Capacitance of the auxiliary capacitor is equal to or larger than ½ of capacitance of the storage capacitor. |
