Abstract: A liquid crystal display panel in one example includes first and second substrates facing each other; a sealant disposed between the first and second substrates, and corresponding to a perimeter of a display area; a first protective layer disposed over the first substrate; a second protective layer disposed over the first protective layer; and an adhesive groove part overlapping the sealant, and including a first contact groove passing through the first and second protective layers, and a second contact groove disposed adjacent to the first contact groove and passing through the second protective layer. Due to the adhesive groove part, the sealant can adhere to each of the first and second protective layers, whereby the attachment force of the liquid crystal display panel can be enhanced.
