摘要： An object of the present invention is to provide a transflective type LCD device in which each of a transmissive area and a reflective area can be driven in an OCB mode, and it is possible to prevent lowering of transmittance and reflectance, and to prevent a pixel from darkening in a case where each of the transmissive area and the reflective area is driven in an OCB mode. The liquid crystal display device of the present invention includes, in each pixel (11), a single nucleus generation section for generating a bend nucleus for promoting a transition of liquid crystal molecules of the liquid crystal layer into a bend alignment. Application of a voltage to the liquid crystal molecules of the liquid crystal layer in the transmissive area and the reflective area carries out a transition from a spray alignment into a bend alignment in response to an applied voltage.
