<p>PURPOSE:To obtain a liquid-crystal display element from which a compound film is removed securely without flawing a substrate or a transparent conductive film, by etching away the compound films at the sealing adhesive connection part and transparent conductive film mutual connection part of each lamination body. CONSTITUTION:An oriented film 4 at the internal-surface circumferential edge part of a lamination body consisting of a glass substrate 1, a transparent conductive film 2, and the oriented film 4 is removed, and a sealing adhesive 3 is applied to this oriented-film removal part 6. This removed part 6 improves the adhesive strength of the sealing adhesive 3 and also serves as an electric mutual connection parts for upper and lower transparent conductive films 2. To form the oriented film 4 and oriented-film removal part 6, a polyimide film with desired film thickness is formed over the entire surface of the transparent conductive film 2 of the glass substrate 2 by spin coating, spray coating, etc. Then, negative type photoresist is used to mask the polyimide film at a part other than said removal part 6. The polyimide film at the removal part 6 is etched by using hydrazine hydrate. Finally, the photoresist is peeled off by a resist peeling liquid.</p> |
