<P>PROBLEM TO BE SOLVED: To overcome the problem wherein a light emitting element has variance in luminance owing to characteristic variations of a driving transistor. <P>SOLUTION: A characteristic of the driving transistor provided to a pixel is specified and according to the results, a video signal inputted to the pixel is corrected. Consequently, a light emitting device which prevents effect of characteristic variations of a transistor and can make sharp multi-gradation display and its driving method can be provided. Further, a light emitting device which suppresses change in the amount of a current flowing between both electrodes of the light emitting element due to temporal variation and can make sharp multi-gradation display and its driving method can be provided. <P>COPYRIGHT: (C)2003,JPO |
