Abstract
A liquid crystal display panel, a sealing performance testing method thereof and a display device are provided. In the liquid crystal display panel, a side of the array substrate facing the opposed substrate is provided with a plurality of independent first conductive portions, a side of the opposed substrate facing the array substrate is provided with a plurality of independent second conductive portions, sealant is an anisotropic conductive adhesive, all of the first conductive portions and all of the second conductive portions are electrically connected through the sealant to form an unclosed conductor surrounding a display region; by testing a resistance value between any two first conductive portions on the array substrate, it can be determined that there is a micro gap or breaking sealant problem upon the resistance value being abnormal.
