摘要:
A liquid crystal display element of the present invention is a vertical alignment type liquid crystal display element (10) comprising an array substrate (22), a counter substrate (24), and a liquid crystal layer (50), which carries out a display by controlling orientations of liquid crystal molecules (52) in the liquid crystal layer (50) by use of transverse electric fields (60). In the liquid crystal display element (10), projections (70) are provided in positions corresponding to boundaries (V1, V2, V3) of orientational regions in the liquid crystal layer (50), on a liquid crystal layer (50) side surface of the counter substrate (24). Each of the protrusions (70) has a taper shape.
