Abstract
A display panel and manufacturing method thereof are provided. The display panel includes a substrate, a first electrode, a hole injection layer, a hole transport layer, an electron blocking layer, an organic electroluminescent layer, a hole blocking layer, an electron transport layer, an electron injection layer, and a second electrode arranged sequentially. The electron blocking layer corresponding to a green sub-pixel region of the organic electroluminescent layer is made of a p-type green light host material. Accordingly, the present invention effectively simplifies a manufacturing process, adjusts and balances charge carriers, and improves device performance.
