| 1. An OCB mode liquid crystal display panel comprising:
a pair of electrode substrates;
a liquid crystal layer which is held between said pair of electrode substrates and has liquid crystal molecules whose alignment
state is controlled within a display area by a drive voltage applied from said electrode substrates; and
a pair of alignment films which are disposed on said electrode substrates in contact with said liquid crystal layer and whose
rubbing directions are set parallel to each other;
wherein said rubbing directions of the pair of alignment films are oriented toward a side of a main diffusion source of impurity
ions,
said liquid crystal layer is formed of a nematic liquid crystal material applied to a liquid crystal filling space surrounded
by a sealing resin layer between said electrode substrates,
said main diffusion source of impurity ions is a sealing member that seals a liquid crystal inlet provided in a part of said
sealing resin layer.
