Organic light-emitting display device

An actively driven OLED comprising:

• a substrate;
• a plurality of organic light-emitting elements and thin film transistors having a power line for driving the organic light-emitting elements;
• wherein each organic light-emitting element comprises an organic light-emitting layer and a pair of electrodes sandwiching the organic light-emitting layer;
• wherein light emitted from the organic light-emitting layer is taken out from one of the electrodes provided at a side opposing the electrode provided at the side of the substrate relative to the organic light-emitting layer;
• wherein each of the power line of the thin film transistor has a convex plane shape and is provided between the organic light-emitting layer and the substrate, and
• wherein the organic light-emitting layer is provided only on a flat portion of the power line.
