The invention provides an LCD panel, an LCD device, and a method for manufacturing a panel. The LCD panel includes an upper substrate and a lower substrate which are arranged opposite to each other. Opposite inner sides of the upper substrate and the lower substrate are respectively provided with a layer of alignment film, a sealant is arranged between the upper substrate and the lower substrate, the alignment film is arranged to extend outside the sealant area, and a surface of the alignment film exposed outside the sealant is provided with a sealing layer. In the invention, the alignment film is arranged to extend outside the sealant, which enable a narrow frame to be used to the LCD panel, and improves the utilization rate of the substrate; moreover, the alignment film exposed outside the sealant is sealed, to completely isolate the alignment film from the outside air; thus, the alignment film cannot be hydrolyzed because of absorbing the outside vapor, thereby ensuring the display quality.
