Abstract:
1. An organic light emitting diode (OLED) display, comprising: a substrate main body, wherein the substrate main body is divided into a display area and a non-display area, and a plurality of pixels is formed in the display area of the substrate main body to display an image; a first thin film transistor and a second thin film transistor on the substrate main body; and an OLED on the substrate main body, wherein: the first thin film transistor includes a gate electrode, an oxide semiconductor layer disposed on the gate electrode in an insulated manner, and source and drain electrodes respectively contacting the oxide semiconductor layer, parts of the source and drain electrodes of the first thin film transistor contacting the oxide semiconductor layer of the first thin film transistor are separated from the gate electrode of the first thin film transistor in a direction that is parallel with the substrate main body by no greater than 5 μm, and at least parts of source and drain electrodes of the second thin film transistor contact an oxide semiconductor layer of the second thin film transistor and overlap a gate electrode of the second thin film transistor along the direction that is parallel with the substrate main body.
