PURPOSE: To easily mass-produce products of homogeneous quality by providing a couple of electrode substrates and a transparent electrode film or insulating film, and forming recesses and projections on the surface of the transparent electrode or insulating film in a grating shape.
CONSTITUTION: Front surface glass 2 and a transparent electrode plate 1 are adhered together and plural spacers 9 are arranged between the plate 1 and a substrate 6 for liquid-crystal display and sealed with a sealant 7 to form a space, where liquid crystal 8 is charged. Insulating films 5 on the reverse of the transparent electrode 1 and on the substrate 6 are coated with photosensitive resin. Then, the films 5 are irradiated with two-luminous-flux interference fringes of laser light, and development, fixation, and washing are carried out to for a grating with recesses and projections at 0.3μm pitch to about 100 depth. Polarizing plates 10 and 11 are stuck on the front surface glass plate 2 and substrate 11. Consequently, products of homogeneous quality are mass-produced.
