摘要:
Embodiments of the present invention relate to a display device. In an embodiment, the display device includes a scanning signal line for transferring a scanning signal, a data line crossing the scanning signal line and transferring a data voltage, a switching transistor connected to the scanning signal line and the data line, a driving transistor connected to the switching transistor, a first transistor connected between the driving transistor and a driving voltage terminal, and a light-emitting element connected between the driving transistor and a common voltage terminal. The first transistor operates in a saturation region, and the driving transistor operates in a linear region. In this way, display characteristics may be improved by reducing deviation of a driving current due to deviation of characteristics of a driving transistor or a driving voltage.
