Claim Text:
1. An organic light emitting diode (OLED) display comprising: a substrate; a first signal line including a first gate electrode disposed directly on the substrate; second and third signal lines crossing the first signal line, the second signal line being a data line to which a data signal is applied and the third signal line being a common power line to which a constant voltage is applied; a first transistor having the first gate electrode connected with the first signal line and having a source electrode connected with the second signal line; a second transistor having a second gate electrode connected with a drain electrode of the first transistor and having a source electrode connected with the third signal line; and an organic light emitting element having a pixel electrode connected with the drain electrode of the second transistor, the source electrodes and the drain electrodes of at least one of the first and second transistors and the pixel electrode of the organic light emitting element connected with the second transistor being formed on a second interlayer insulating layer with a same material, wherein the source electrodes, the drain electrodes, and the pixel electrode are thinner than the data line, and the source electrodes and the drain electrodes of the first and second transistors being thinner than the third signal line.
