Abstract:
1. A liquid crystal display device comprising: a first substrate and a second substrate arranged in parallel with each other at a distance; a liquid crystal layer formed by filling liquid crystal material having negative dielectric anisotropy between the first substrate and the second substrate; a first electrode and a second electrode formed on opposing surfaces of the first substrate and the second substrate respectively to define a pixel by at least one of them; an alignment film formed on at least one of the first substrate and the second substrate and having an alignment defining force to align the liquid crystal molecules of the liquid crystal layer perpendicularly to the film surface; projections formed on the opposing surface of the first electrode; a first domain defining means provided on the opposing surface of the first electrode and having a pattern elongated along one direction in at least a local area within a substrate surface, and for tilting the liquid crystal molecules in a neighborhood of an edge of the first domain defining means to such a direction that end portions positioned far from the first electrode go away from the first domain defining means when a voltage is applied between the first electrode and the second electrode; and a second domain defining means provided on the opposing surface of the second electrode and arranged in parallel with or to be overlapped with the first domain defining means in at least a local area within the substrate surface when viewed along a normal direction of the substrate, and for tilting the liquid crystal molecules on an inside of the second domain defining means to a direction that is substantially parallel with a length direction of the second domain defining means.
