Abstract
The present application provides a display panel including: a substrate, a thin film transistor layer, an insulation layer, an anode layer, an electron transport layer, and a cathode layer. The thin film transistor layer includes an auxiliary transistor. A first cathode auxiliary hole is defined in the insulation layer. The anode layer includes a connection portion disposed in the first cathode auxiliary hole and electrically connected to the auxiliary transistor. The electron transport layer includes an electron transport portion disposed to correspond to the connection portion. The cathode layer includes a cathode auxiliary electrode connected to the electron transport portion. The present application can prevent an issue of uneven brightness due to voltage decrease and improves quality of the display panel.
