The storage capacitor Cst may be connected to the switching TFT Ts and a driving voltage line PL. The storage capacitor Cst may store a voltage corresponding to a difference between a voltage received from the switching TFT Ts and a driving voltage ELVDD supplied to the driving voltage line PL.

The driving TFT Td may be connected to the driving voltage line PL and the storage capacitor Cst. The driving TFT Td may control driving current flowing through the OLED from the driving voltage line PL according to a value of the voltage stored in the storage capacitor Cst. The OLED may emit light having a predetermined luminance due to the driving current. The OLED may emit, for example, red, green, blue, or white light.

Referring to FIG. 2, the pixel P is shown as including two TFTs and one storage TFT. In some implementations, various modifications may be made. For example, the pixel circuit PC of the pixel P may include three or more TFTs or may include two or more capacitors Cst.

Referring back to FIG. 1, a peripheral area PA may be located outside the display area DA. For example, the peripheral area PA may surround the display area DA. The portion of the peripheral area PA where the pixels P are not located may be a non-display area where no image is provided.

A driving circuit including, for example, a first driver, a second driver, a terminal unit 40, a driving power supply line 60, and a common power supply line 70, may be located in the peripheral area PA. The first driver may include first and second light-emitting driving circuits 30 and 32. The second driver may include first and second scan driving circuits 20 and 22.
