Beschreibung
Zusammenfassung:	PURPOSE:To increase the adhesive strength of substrates and to prevent the deterioration of the transparency by treating the opposing surfaces of the substrates each composed of polymer films with said or alkali and by adhering polymer films to the treated surfaces. CONSTITUTION:A substrate formed by sticking a polyethylene film 9 to one principal surface of a polyester film 7 with a polyester adhesive 8 has high transparency because the principal surface of the film 7 undergoes no chemical treatment. The principal surface of the substrate 10 not protected with the film 9 is made finely uneven 11 after chemical treatment. A patterned electrically conductive transparent film 13 is formed on the uneven surface, and a polyamide film 16 is laid and rubbed with buff to form an orientation controlling film. The transparency of the substrate is not deteriorated by laying the polyamide film on the uneven surface 11. A laminated structure may be provided to the polyamide film.
