The present invention provides to an in-plane-switching (IPS) mode liquid crystal panel, which comprises: a first substrate, a second substrate, a coplanar transparent electrode layer and a liquid crystal layer. The first and second substrates have a first alignment film and a second alignment film, respectively. The coplanar transparent electrode layer is disposed onto the second alignment film. The liquid crystal layer is disposed in a space between the first alignment film of the first substrate and the coplanar transparent electrode layer of the second substrate. The liquid crystal layer comprises dual-frequency liquid crystal molecules and dual-frequency reactive mesogens/monomers. The liquid crystal panel of the present invention can overcome the problems of pollution and static electricity generated from the rubbing alignment in the in-plane-switching (IPS) mode, so as to simplify the manufacturing process and provide the advantages of high contrast, high response speed and wide viewing angle.
