The device also calculates gradation deterioration characteristics based on the measurement information and the relationship between a gradation value and a luminance value when the pixel circuit is in a correction reference state. A deterioration value calculation calculates a conversion efficiency deterioration value of conversion efficiency for the light-emitting device to convert a driving current supplied for a gradation value into a luminance to generate conversion efficiency deterioration characteristic information. Finally, the device calculates current amount deterioration value that calculates a current amount deterioration value regarding deterioration of a driving current of the pixel circuit based on the gradation deterioration characteristic to generate current amount deterioration characteristic information of the prescribed pixel circuit.
