    Abstract: The present application discloses a manufacturing method of a display panel and a display panel. The manufacturing method includes the steps: forming a color filter layer on a substrate; confirming a colorfilter-to-be-stripped in the color filter layer; and stripping the colorfilter-to-be-stripped by using a selected stripping liquid; the color filter layer includes a first color filter, a second color filter and a third color filter; and the colorfilter-to-be-stripped includes one or two of the first color filter, the second color filter and the third color filter, and the method of stripping the colorfilter-to-be-stripped by the selected stripping liquid includes: letting the colorfilter-to-be-stripped react with the selected stripping liquid, and stripping the colorfilter-to-be-stripped by the selected stripping liquid, and forming a protective layer on the surface of the color filters except the colorfilter-to-be-stripped.

    Abstract: Problem to be SolvedTo provide a composition that can efficiently remove a photoresist adhering to an edge portion and a back surface of a substrate, in a process of producing a mask which is used when the substrate is subjected to etching treatment to have an element, a circuit etc., formed thereon using the photoresist.SolutionThe composition for removing a resist of the present invention is a composition comprising a surfactant and a solvent, wherein the composition contains, as the surfactant, at least the following component (A).Component (A): a polyglycerol derivative represented by the following formula (a): RaO—(C3H5O2Ra)n—Ra  (a) wherein n represents the number of the repeating units, and is an integer of 2 to 60; and Ra identically or differently represents a hydrogen atom, a C1-18 hydrocarbon group or a C2-24 acyl group, provided that at least two of the (n+2) number of Ra are C1-18 hydrocarbon groups and/or C2-24 acyl groups.
