    Abstract: The present invention relates to a display panel and a manufacturing method of the display panel. A charge generation layer of the present invention is produced using a mixture of an n-type organic material, a p-type organic material, and a polar solvent. The n-type organic material and the p-type organic material are mixed to form the charge generation layer, so that a contact area between the n-type organic material and the p-type organic material is increased. Accordingly, the present invention improves the transfer efficiency of charges, improves chances of separation of electrons and holes, and finally improves the charge generation efficiency of the charge generation layer. Therefore, the present invention avoids the use of a fine metal mask (FMM) in an evaporation process. Consequently, the present application reduces production costs and can be used in large-size-screen G8.6 production lines.
