Abstract: An exemplary method for manufacturing a liquid crystal display (LCD) panel (20) includes: providing a first and a second substrates (21, 22), each substrate including a display region (212, 222), a periphery region (214, 224) surrounding the display region, and a sealant adhesive region (215, 225) located between the display region and the periphery region; forming data lines (223) and gate lines (221), and the data lines and gate lines extending to the periphery region; forming an alignment film (240) on the second substrate, the alignment film covering the display region and the periphery region; rubbing the alignment film; forming a sealant; injecting liquid crystals; attaching the two substrates to form an LCD panel; etching the alignment film to expose end portions of the data lines and gate lines.
