ETCHING METHOD FOR MANUFACTURING DISPLAY PANEL WITH CURVED SHAPE FROM SIDE TO SIDE

摘要

The present invention relates to a substrate etching method for etching the flat surfaces of a first substrate and a second substrate formed between liquid crystal layers to manufacturing a curved display panel. The method includes the steps of: forming a protection layer while a driving circuit unit is coupled to a display panel unit to protect the areas with the liquid crystal layers; protecting the driving circuit unit from an etchant; masking the non-etching areas on the first and second substrates; and etching the flat surfaces of the first and second substrates while the masked display panel is fixed. Accordingly, the present invention can acquire a thin-film substrate without damaging the driving circuit unit during the etching process. The thin-film substrate can be used to manufacture the curved display panel.
