The invention relates to a display panel and a manufacturing method thereof. The display panel comprises a substrate, a first
photoresist layer and a
first light-emitting function part, a plurality of first electrodes arranged at intervals and a plurality of first pixel openings used for at least partially exposing the corresponding first electrodes respectively are arranged on the substrate, the first
photoresist layer is arranged on the substrate, and the
first light-emitting function part is arranged on the first
photoresist layer. The first photoresist layer is provided with first
evaporation openings communicated with the first pixel openings, and the
first light-emitting function parts are arranged in the first
evaporation openings and the first pixel openings and cover the corresponding first electrodes. The first
evaporation openings are communicated with the first pixel openings to
expose at least part of the first electrodes, so that the first light-emitting function parts are formed on the first electrodes through the first evaporation openings, sub-pixels of corresponding colors can be correspondingly formed, a
metal mask plate does not need to be used, and the manufacturing cost is reduced. The problems that the aperture opening ratio of the manufactured display panel is limited and a large-size display panel is difficult to manufacture when the display panel is manufactured by using a
metal mask plate are solved.
