。DETAILED DESCRIPTION OF THE INVENTION <Industrial Application Field> The present invention relates to a method of manufacturing an electrode plate for a display device used in a display input device using a color liquid crystal display.

きている。同時に大画面化しつつある。<Prior Art> In order to display high-density liquid crystal displays, pitches of pixels and terminal parts are required to be around 1100I1. At the same time, screens are becoming larger.
従って、液晶駆動の観点から透明電極の低抵抗化と、薄
型化という観点から駆動用ＩＣとの表面実装という２つ
の要求が特に強くなってきている。Therefore, two demands are becoming particularly strong: low resistance of transparent electrodes from the viewpoint of driving liquid crystals, and surface mounting with driving ICs from the viewpoint of thinning.
これら要求を満足させるため、透明電極の一部に低抵抗

属薄膜を形成し、表面実装用途に対応することは公知の
技術である。In order to satisfy these demands, a fine line pattern of a thin metal film with a width of several tens of micrometers is provided on a part of the transparent electrode as an auxiliary conductor to reduce resistance, or a thin metal film is formed on the terminal part of the liquid crystal panel. It is a known technology to accommodate surface mount applications.

樹脂の保護層を設けることは一般に行われている。In color liquid crystal displays, this display is significantly superior to those in which transparent electrodes are formed on color filters in terms of liquid crystal driving and display quality. In order to pattern the transparent electrode by etching and for the purpose of imparting acid resistance to the color filter, a protective layer of organic resin is generally provided between the color filter and the transparent electrode.

クレを発生する欠点があった。<Problems to be Solved by the Invention> An electrode plate in which a protective layer of organic resin is formed on a color filter formed by printing or dyeing, and then a transparent electrode is further formed on the protective layer, can be produced in a subsequent process. It has the disadvantage of causing wrinkles and blisters during heat treatment.

傷をつけ易いためである。On the other hand, although polyimide and silicone resins are heat resistant, they are extremely expensive and cannot be used as protective layer materials; A problem arises in the electrical connection of the transparent electrode because there is a resin layer between the transparent electrode and the substrate, and the transparent electrode is easily damaged by pressure from above.

理する方法及び物を、提供しようとするものである。In order to solve the above-mentioned problems, the present inventor proposed a new electrode plate using a polypeptide photosensitive resin such as gris, gelatin, or casein, or a photosensitive resin with a phenol borac epoxy resin skeleton as a protective layer. . However, although this electrode plate is almost at a practical level,
In some cases, the adhesion between the transparent electrode and the protective layer or glass transparent substrate was weak. In addition, in order to increase the adhesion to the protective layer of peptide resin such as gelatin, it was necessary to perform reverse sputtering on the surface of this protective layer to promote surface cleaning and polymerization by sputtering. However, the reverse sputtering mechanism not only increases the equipment cost, but also
This treatment has the disadvantage of reducing the production capacity of electrode plates.The present invention seeks to provide a method and product for treating the surface of a protective layer without using reverse sputtering.

The present invention relates to an electrode plate for a display device and a method for manufacturing the same, which is characterized in that a transparent electrode is formed after surface treatment with a coupling agent.

れた。<Effects of the Invention> In the present invention, the overcoat layer and the surface of the transparent substrate are surface-treated with a coupling agent before laminating the transparent electrode and the inorganic oxide layer. Adhesive strength is significantly improved. The present invention can eliminate the peeling of transparent electrodes and inorganic oxide layers that conventionally occurred during the cell folding process after sealing a liquid crystal panel. In addition, the conventionally necessary reverse sputtering process is no longer necessary, improving productivity. In addition, by coating with the coupling agent, the smoothness of the substrate surface was slightly improved, and the secondary effect was that the resistance value of the transparent electrode was improved by about 10% to 30%.
