After creating color filter substrates in the (CF) process and bonding these substrates with the liquid crystal sandwiched between them (assembly process) After separating multiple thin liquid crystal display panels formed on one substrate (breaking process) Each thin liquid crystal display panel was thinned by a chemical treatment (etching) process or a polishing process on the front and back glass substrates to produce a thin liquid crystal display panel having a panel thickness of about 0.6 mm. As a result, half of the glass as a raw material is discarded in the chemical treatment process or the polishing process.

なお、一般の半導体素子基板の製造方法において、厚みの薄い部分を有する半導体素子基板に補強材を貼り付けて製造を行うものがある(例えば特許文献1参照)。   In addition, in a general method for manufacturing a semiconductor element substrate, there is a method in which a reinforcing material is attached to a semiconductor element substrate having a thin portion (for example, refer to Patent Document 1).
