A drive unit of the organic light-emitting device is provided, which can control the color deviation between the panel by applying the property of the driving transistor of the panel to the gradation voltage or the grayscale reference voltage. A driving transistor is connected to the power line for operating the organic light-emitting device. The gate and source of the driving transistor are connected. The property measurement part(10) comprises the current source or the current sink. The current source or the current sink is connected to the source of the driving transistor. The current amount is controlled so that the fixed reference voltage can be outputted from the source of the driving transistor. The voltage generation part produces the gradation voltage or the grayscale reference voltage by utilizing the output outputted from the driving transistor. |
