ABSTRACT:
A liquid crystal display panel having a display area comprises a first substrate, a second substrate, a sealant, a liquid crystal layer, and a light-shielding layer. The sealant is disposed between the first substrate and the second substrate. The liquid crystal layer is disposed in a space defined by the first substrate, the second substrate and the sealant. The light shielding layer is disposed on a first outer surface of the first substrate or a second outer surface of the second substrate, wherein the light shielding layer and the display area are not overlapped. In addition, the liquid crystal display panel further comprises a protection layer. Since the protection layer encapsulates the light-shielding layer, out-diffusion of dye within the light-shielding layer is effectively prevented.
