A manufacturing method of a display panel includes following steps. A pixel array substrate and an opposite substrate are provided. An interface layer is formed on the pixel array substrate or on the opposite substrate, and the interface layer includes at least one dianhydride compound, a polyimide precursor obtained by subjecting at least one diamine compound to a reaction, and a polyimide compound obtained by subjecting the polyimide precursor to imidization. The polyimide compound includes at least one diamine compound having a photo-reactive side chain.
