<P>PROBLEM TO BE SOLVED: To provide a method for manufacturing a display device which can manufacture an ultrathin glass substrate without advancing a crack. <P>SOLUTION: To a glass substrate 111, the deposition of a thin film 112 of a thin film transistor, an organic EL element or like is carried out, and the sealing is carried out by a non-osmotic membrane (step S11). A sealing material 114 for preventing the intrusion of an etching solution is formed on the deposition surface of the thin film 112 (step S12). Succeedingly, the glass substrate 111 is immersed in an etching solution, the melting of the glass substrate 111 is carried out until the thickness is set to 0.2 mm (step S13). Next, the glass substrate 111 is bent so that the surface on which the thin film 112 has been formed may turn into a concave when being seen in a cross section perpendicular to a cutting line 113, a scribing wheel 115 is pressed along the cutting line 113, and the glass substrate 111 is cut (step S14). Each of the glass substrate 111 which has been cut is used as an organic EL display panel 117 (step S15). <P>COPYRIGHT: (C)2012,JPO&INPIT |
