Abstract

A novel display panel having good functionality is provided. Provided are a display panel and a manufacturing method of the display panel, including forming an insulator including at least a first opening portion and a second opening portion over a substrate, forming a first material layer including an organic compound of a first light-emitting element in the first opening portion and a second material layer including an organic compound of a second light-emitting element in the second opening portion by a wet process, forming a first resist mask and a second resist mask respectively over the first material layer and the second material layer selectively, and forming a third material layer by processing the first material layer with the first resist mask, and forming a fourth material layer by processing the second material layer with the second resist mask. As the organic compounds of the light-emitting elements, a hole-transport material, a light-emitting material, and the like can be used.
