发明名称 Reflection member and liquid crystal display device using the same
摘要 A reflection member applicable to a liquid crystal display device is disclosed. The liquid crystal display device includes a reflective pixel electrode 19 formed on a matrix array substrate 11, a counter electrode provided opposite to the reflective pixel electrode 19 on a counter substrate 22, and a liquid crystal layer 27 held between the reflective and counter electrodes 19 and 25. The reflective pixel electrodes 19 have convex and concave portions 20a and 20b as light scattering elements. Centers of the convex portions 20a are disposed in lattice points of hexagonal lattices. Lattice parallel vectors are rotated around the radius center by an angle of about 60°, defined between the lattice points at both end portions of the pixel electrode, but, more suitably, the one ranging from 51.4° to 68.6°, i.e., 60°±8.6°. Such disposition of the light scattering elements reduces two dimensional periodicity as to the convex portions. Thus coloring caused by optical interference between the convex portions 20 can be suppressed. Excellent display quality with uniform brightness is achieved by making distances between the light scattering elements consistent with those from which a optimal slant angle distribution can be obtained.
