  • Patent number: 10551683
    Abstract: A display panel and a method for fabricating the same are disclosed. The display panel includes a first substrate, a second substrate which is arranged oppositely to the first substrate, a frame sealant which is arranged between the first substrate and the second substrate, and a black matrix which is arranged on the second substrate. A projection of the black matrix on the first substrate does not overlap a projection of the frame sealant on the first substrate. This facilitates completely exposing the frame sealant to a curing UV light. This improves a curing efficiency of the frame sealant, increases the adhesiveness of the frame sealant, and avoids the problem of liquid crystal leakage due to breakage of the frame sealant.
