Abstract:
A display panel (100) and a manufacturing method therefor. In the display panel (100), an organic light-emitting structure layer (16) and a package structure layer (17) are formed on a pixel defining layer (15) and wrap the entire surface of a through hole (21). The method comprises: forming the through hole (21), and then wrapping the surface of the through hole (21) with the organic light-emitting structure layer (16) and the package structure layer (17), so that the package structure layer (17) wraps the circumference side of the through hole (21) and thus corrosion to a metal layer of a display area by moisture along the space between layers of a cross-section of the through hole can be avoided.
