PROBLEM TO BE SOLVED: To solve the problem in which variations in the luminance of a light emitting element are caused by variations in the characteristics of driving transistors.SOLUTION: A storage medium is included for storing an interpolation function derived from a current value obtained by current measuring means electrically connected to a pixel part, when at least one of light emitting elements is in an on-state. A correction circuit has a function of identifying the characteristics of each of driving transistors provided in a pixel, by using the interpolation function stored in the storage medium and correcting a video signal input to the pixel part. The current measuring means is removed from the pixel part after the current value is obtained.SELECTED DRAWING: Figure 1 |
