PROBLEM TO BE SOLVED: To provide a technology to perform luminance dispersion correction using a small correction value table reduced in error. SOLUTION: In a first step, a plurality of electron-emitting devices are driven by a drive signal corresponding to a first gradation level and luminance dispersion at the first gradation level is measured. In a second step, one or more electron-emitting devices are selected as target devices from the plurality of electron-emitting devices, the target devices are driven by the drive signal corresponding to each gradation level, and the luminance of the target devices for each gradation level is measured. In a third step, the target devices are driven by the drive signal having a voltage amplitude of the drive signal corresponding to each gradation level multiplied by a constant, and the luminance of the target device for each gradation level is measured. Then, a correction value for each gradation level of each electron-emitting device is calculated from a luminance ratio of the luminance measured in the second step to the luminance measured in the third step and the luminance dispersion measured in the first step.
