ABSTRACT:
Aspects of the invention can provide a transflective liquid crystal display device of vertical alignment mode capable of suitably controlling the direction that liquid crystal molecules are tilted. The liquid crystal display device can include a liquid crystal layer interposed between a pair of substrate and transmissive and reflective display regions in each dot region. An insulating film for varying the thickness of the liquid crystal layer in the reflective and transmissive display regions is provided. On a substrate having the insulating film formed thereon, an electrode slit for controlling the alignment of the liquid crystal molecules can be formed in the reflective display region. Similarly, a convex portion for controlling the alignment of the liquid crystal molecules can be formed in the transmissive display region.
