PURPOSE: To enable the mass production of an excellent product having uniform quality by providing a pair of electrode substrates, oriented films and liquid crystal to the titled device, forming the oriented films of photosensitive positive type photoresist and providing grating-shaped ruggedness on the surface thereof.
CONSTITUTION: Front glass 3 and transparent electrodes 1 are adhered and plural spacers 10 are sealed between said glass and the substrate 7 for the liquid crystal display by a sealant 8. The liquid crystal is sealed in the space thus formed. The oriented film 2 is provided to the electrodes 1. TFT elements 4 (TR for switching of picture element electrodes) and a picture element part 5 are disposed to the substrate 7. The oriented film 6 is formed thereon. Polarizing plates 11, 12 are adhered to the glass 3 and the substrate 7. The films 2, 6 are formed by coating the photosensitive resin on the substrates then irradiating two-beam interference fringes of laser light thereto and developing, fixing and rinsing the resin to form the grating having 0.3μm pitch and about 100 depth. The mass production of the excellent product having uniform quality is thus executed.
