摘要： An embodiment of the present invention provides a display panel. The display panel includes a driving circuit layer, a first electrode layer, an auxiliary electrode layer, a pixel definition layer, and an electron transport layer disposed in a stack. The electron transport layer is connected to the auxiliary electrode layer through a first via hole defined on the pixel definition layer. By setting an energy level difference between a lowest unoccupied molecular orbital of the electron transport layer and a work function of the auxiliary electrode layer to 2.0 eV or less, it reduces an injection barrier between the auxiliary electrode layer and the electron transport layer, and relieves unevenness of luminescence of the display panel.
