Abstract
Thin film transistors TFT and TFT for driving elements are formed in parallel between a power source line and an organic EL element, and active layers of the transistors TFT and TFT are spaced apart in a scanning direction of a laser used for annealing for polycrystallization. As a result, the annealing conditions for the transistors TFT and TFT will not be exactly the same, thereby reducing the chance of a same problem being caused in both transistors TFT and TFT
