Abstract
An organic light emitting display is disclosed. In the disclosure, only one switching TFT among TFTs constituting a pixel is implemented as an NMOS type TFT, and at least some of a driving TFT and the remaining switching TFTs are implemented as a PMOS type TFT. Therefore, the disclosure simplifies TFT process steps and provides an organic light emitting display suitable for realizing a high resolution pixel implementation.
