In a pixel driving device that drives a plurality of pixels, each pixel includes a light emitting element and a pixel driving circuit comprising a driving device having one end of a current path connected to one end of the light emitting element and having another end of the current path to which a power-source voltage is applied. Provided in a controller is a correction-data obtaining function circuit which obtains a first characteristic parameter relating to a threshold voltage of the driving device of each pixel based on a voltage value of each data line after a first detection voltage is applied to each data line connected to each pixel, and a current is caused to flow through the current path of the driving device through the each data line with a voltage of another end of the light emitting element being set to be a first setting voltage.
