PROBLEM TO BE SOLVED: To reduce loss power in an active element controlling luminescence of respective pixels of an organic EL display device. SOLUTION: One pixel of an organic EL element is provided with two active elements of a selection transistor 3 and a drive transistor 5. Then, the selection transistor 3 is connected to a gate line 1 and a drain line 2. Further, the drive transistor 5 is connected to the selection transistor 3. Then, three first-third EL elements 11, 12, 13 are serially connected to the drive transistor 5. Then, even when a current flowing through respective EL elements 11, 12, 13 is reduced, required luminance is obtained. Then, the current flowing through the drive transistor 5 is reduced, and loss potential in the drive transistor 5 is lowered. Thus, the loss power in the drive transistor 5 is reduced. |
