An IPS (in-plane switching) liquid crystal display has a color filter substrate (3), a TFT (thin film transistor) substrate (8), and a liquid crystal layer (7) interposed therebetween. The TFT substrate includes a TFT plate (5), a protrusion layer (6), and an electrode matrix. The electrode matrix includes a plurality of transversely disposed gate lines (22), a plurality of longitudinally disposed data lines (21), switching elements, a plurality of common electrodes (27), and a plurality of pixel electrodes (28). The protrusion layer has a plurality of protrusion portions (61). The common and pixel electrodes are formed on the protrusion portions in one-to-one correspondence to provide an array of protrusive electrodes that generate a strong and highly uniform parallel electric field. This provides better picture quality, and can lower power consumption and/or yield a higher aperture ratio.
