Zusammenfassung:PROBLEM TO BE SOLVED: To provide an organic EL (electroluminescence) display device in which light emitted by an organic EL element whose luminance is adjusted for detection of deterioration does not stand out as compared to light emitted by other organic EL elements, thereby not producing an unpleasant feeling for users. SOLUTION: A calculation part in a display control part 104 sets, for a target pixel 302, a driving signal Out(C)=V. For a peripheral pixel 301 horizontally located immediately before the target pixel 302, the calculation part calculates a driving signal Out(C-1)=In(C-1)-(V-In(C))/2. For a peripheral pixel 303 horizontally located immediately after the target pixel 302, the calculation part calculates a driving signal Out(C+1)=In(C+1)-(V-In(C))/2. COPYRIGHT: (C)2011,JPO&INPIT
