Display panel and method for fabrication thereof

A fabrication method of a display panel, comprising:

• forming a sealing material layer and a substrate sequentially on a supporting substrate, wherein the substrate has a display region and a non-display region;
• forming a pixel array in the display region of the substrate and forming a peripheral circuit in the non-display region of the substrate, wherein the peripheral circuit and the pixel array are electrically connected;
• forming a protective layer on the substrate to cover the peripheral circuit and the pixel array;
• forming a plurality of openings in the protective layer in the non-display region so as to expose the substrate;
• introducing a gas and performing a treatment procedure to the sealing material layer, to reduce adhesion between the sealing material layer and the substrate, wherein the gas is introduced into the substrate through the openings and diffuses to the sealing material layer;
• and
• separating the substrate and the sealing material layer.
