摘要： A light-emitting element (OLED) is caused to emit light with preferred brightness and gradation level depending on display data. During a precharge period, a data driver applies a precharge voltage (Vpre) to a capacitor (Cs) via a data line (Ld). After the application of the precharge voltage, a voltage converter reads, after a transient response period (Ttrs), a reference voltage Vref to generate a compensation voltage (a·Vref). A voltage calculator compensates, based on the compensation voltage (a·Vref), an original gradation level voltage Vorg having a value in accordance with display data generated by a gradation level voltage generator. As a result, the voltage calculator generates a compensated gradation level voltage Vpix corresponding to a variation amount of an element characteristic for a transistor Tr13 for driving light emission to apply the compensated gradation level voltage Vpix to a data line Ld.
