Abstract
Display panels, manufacturing methods thereof, and display devices are provided. The display panel includes a substrate, a thin film transistor layer, an insulation film, a first conductive layer disposed above the insulation film, a light-emitting layer including an organic material and disposed above the first conductive layer, a functional layer disposed above the light-emitting layer, and a second conductive layer disposed above the functional layer. The insulation film includes protrusions protruding upwards. The first conductive layer includes pixel electrodes and auxiliary electrodes insulated from the pixel electrodes. The auxiliary electrode is disposed above the protrusion and includes a protruding part having a height higher than that of the pixel electrode in a vertical direction. The functional layer includes through holes disposed above the protrusions. The second conductive layer is connected to the protruding parts via the through holes.
