ABSTRACT:
The invention provides a liquid crystal display device having a wide viewing angle for transmissive display and reflective display. The liquid crystal display device according to the invention can include a homeotropic liquid crystal layer interposed between a pair of substrates. The liquid crystal display device has a transmissive display area and a reflective display area in each dot area. A liquid crystal layer thickness-adjustment layer can be interposed between at least the substrate of the pair of substrates and the liquid crystal layer. The liquid crystal layer thickness-adjustment layer reduces the liquid crystal layer thickness of the reflective display area in comparison with the liquid crystal layer thickness of the transmissive display area. On the substrate opposing the substrate with the liquid crystal layer thickness-adjustment layer, protrusions protruding from the inner surface of the substrate to the liquid crystal layer are formed.
