Abstract
The present invention provides a display panel. In the display panel, a first driving thin-film transistor is electrically connected to a first organic light-emitting diode (OLED) device, and a second driving thin-film transistor is electrically connected to a second organic light-emitting diode (OLED) device; the first driving thin-film transistor includes a first active layer, and a channel portion of the first active layer has a first aspect ratio; the second driving thin-film transistor includes a second active layer, and a channel portion of the second active layer has a second aspect ratio; and the first aspect ratio is smaller than the second aspect ratio.
