Abstract:
1. A liquid crystal display device, comprising: a first substrate and a second substrate for sandwiching a liquid crystal having a negative dielectric constant anisotropy, wherein said first substrate includes thin film transistors and domain regulating means, wherein said domain regulating means is a protrusion-like structure on said first substrate, and said protrusion-like structure is formed of a member that is the same as at least one member constituting said thin film transistors, and wherein said domain regulating means includes a first conductive layer of a material that is the same as that of a gate electrode of said thin film transistor, a first insulating layer of a material that is the same as that of a gate insulating layer of said thin film transistor and which covers said first conductive layer, a second conductive layer of a material that is the same as that of source/drain electrode of said thin film transistor and which is on said first insulating layer, and a second insulating layer of a material that is the same as that of a protection insulating layer of said thin film transistor and which covers said second conductive layer.
