1. A method of manufacturing a liquid crystal display panel, comprising:
providing a first liquid crystal display panel, the first liquid crystal display panel defining a first display area of a first size, and the first liquid crystal display panel comprising a color filter substrate, a liquid crystal layer, and an array substrate stacked in said order;
cutting the color filter substrate so that the first liquid crystal display panel is in a vacuum-broken state;
injecting liquid crystal in the liquid crystal layer after cutting the color filter substrate; and
coating sealant enclosing the liquid crystal layer and extending to a side of the color filter substrate away from the array substrate to cover part of the first display area on an area of the array substrate not covered by the color filter substrate, wherein the sealant is in direct contact with the liquid crystal layer but does not extend between the array substrate and the color filter substrate, thereby obtaining a second liquid crystal display panel having a second display area of a second size, the second size being less than the first size.
