Abstract
A flexible display panel and a manufacturing method thereof are provided. By filling a protective film in a stress concentration area of an inorganic film layer at a corner of a dam, a slope of a side wall of the dam can be effectively reduced, and stress concentration effect of the inorganic film layer in an upper packaging structure is reduced to a certain extent. When the protective film is subjected to stress, it can effectively relieve the stress and weaken or even eliminate stress effect of the packaging structure on an anode layer at a corner of the dam.
