Abstract: A manufacturing method of a display panel includes forming pixels in a display area of a substrate, and forming a metal wiring and a dam portion in a non-display area of the substrate, forming an encapsulation layer using an inorganic insulating material and an organic insulating material to cover the display area of the substrate and inspecting presence or absence of a remaining layer including the organic insulating material, which is formed in a remaining area of the encapsulation layer except for the display area, using a filter having a predetermined wavelength range.
