Abstract:
The present invention lowers leaking of light at the time of performing a black display of VA-type liquid crystal display device and, at the same time, prevents lowering of a numerical aperture. In a liquid crystal display device having a liquid crystal display panel which sandwiches a liquid crystal material between a first substrate having a pixel electrode and a second substrate having a counter electrode, the second substrate includes an orientation control projection which is formed by forming a conductive film on the second substrate, by forming an insulation film on the conductive film and, thereafter, by patterning the insulation film, and a light shielding layer which is formed by patterning the conductive film using the orientation control projection as a mask.
