NOVELTY - Manufacture of a thin film involves arranging an inorganic metal salt thin film layer made of an inorganic metal salt on one surface of the support substrate. USE - Manufacture of thin film (claimed) used for substrate detachment from carrier substrate during manufacture of flexible display panel. Uses include but are not limited to liquid crystal display, plasma display panel, organic light-emitting device, and organic LED. ADVANTAGE - The method is economical. The thin film has low thermal expansion coefficient and stimulation of light and heat energy, and facilitates desorption due to outgassing inside the inorganic metal salt thin film layer.
