发明名称 Liquid crystal panel motherboard needing slicing and manufacturing method thereof
摘要 A liquid crystal panel motherboard need slicing is proposed. The liquid crystal panel motherboard includes a main substrate disposed at one side of a CF (2) and a main substrate disposed at one side of a TFT (1). The liquid crystal panel motherboard can be sliced to be at least two liquid crystal panels including a CF substrate (20) and a TFT substrate (10). Metallic terminal parts are formed on each TFT substrate (10). A soft protective film (24) is disposed on a touching area (22) connected to each metallic terminal part of the TFT substrate (10) connected to the CF substrate (20). The soft protective film (24) has a certain thickness and leans against its corresponding metallic terminal part on a main substrate at the side of the TFT (1). A manufacturing method of the liquid crystal panel motherboard needing slicing is also proposed. The present invention has an advantage of preventing the metallic terminal part of the TFT substrate from being scraped when the liquid crystal panel motherboard is sliced, thereby improving the production yield rate.

主权项 1. A liquid crystal panel motherboard needing slicing, comprising: a main substrate at one side of a thin film transistor (TFT) and a main substrate at one side of a color filter (CF), the main substrate at the side of the TFT disposed on top of the main substrate at the side of the CF, the main substrate at the side of the TFT and the main substrate at the side of the CF being overlapped, and the liquid crystal panel motherboard being capable of being sliced into at least two liquid crystal panels comprising a CF substrate and a TFT substrate along a first slicing line and a second slicing line; a plurality of metallic terminal parts formed on the TFT substrate of each of the liquid crystal panels, a soft protective film disposed on a contact area which touches each of the plurality of metallic terminal parts disposed on the TFT substrate corresponding to the CF substrate, and an area where the soft protective film is coated on the CF substrate being larger than an area of a corresponding metallic terminal part, wherein the contact area is located between the first slicing line and a second slicing line; wherein the soft protective film comprises a certain thickness and leans against a corresponding metallic terminal part on a corresponding TFT substrate for preventing a metallic terminal in the metallic terminal part on the TFT substrate from being scraped when the liquid crystal panel motherboard is sliced, wherein the soft protective film comprises strips of soft protective films coated at intervals on the contact area of the CF substrate which corresponds to the metallic terminal part.
