Abstract
The weight and thickness reduction of a display panel can be realized without reducing the substrate size and lowering the productivity. To produce a display panel, there are performed a panel producing step for manufacturing a display panel using substrates each having a predetermined wall thickness; and a chemical treatment step for immersing the display panel into a chemical solution and removing a fixed amount of the surface of the substrates by a chemical reaction so as to reduce the wall thickness, wherein in the panel producing step, the display panel is produced by forming an electroluminescence element on one substrate having a predetermined thickness, and in the chemical treatment step, the display panel is immersed into the chemical solution while the electroluminescence element is protected.
