Abstract
An OCB mode liquid crystal display panel comprises a pair of electrode substrates, a liquid crystal layer which is held between the pair of electrode substrates and has liquid crystal molecules whose alignment state is controlled within a display area by a drive voltage applied from the electrode substrates, and a pair of alignment films which are disposed on the electrode substrates in contact with the liquid crystal layer and whose rubbing directions are set parallel to each other. The rubbing directions of the pair of alignment films are oriented toward a side of a main diffusion source of impurity ions.
