る。 Liquid crystal display devices have low power consumption, small size,
Because they are lightweight, they have become extremely popular in recent years as calculators, electronic watches, and display devices for electronic devices. Furthermore, there is a growing demand for use as a display device for small personal computers and the like. On the other hand, when a liquid crystal panel is used as a display element, there is a drawback that the amount of displayed information is generally small. This drawback is attributable to the fact that liquid crystals have poor contrast characteristics with applied voltage and are not well suited for multiplex driving. Currently, the limit value for multiplex driving of liquid crystals is thought to be about 20 to 30 digits. Several methods have been devised to improve this multiplexing characteristic and increase the amount of displayed information. One way to do this is to correct the multiplex characteristics of liquid crystals by combining transistors, diodes, and other electrical elements with liquid crystals, making it possible to drive multi-digit multiplexes of hundreds of digits or more. There is a method. Among them, it consists of a three-layer structure of metal-insulator-metal.
Liquid crystal display devices using MIM are currently attracting particular attention because they are capable of multi-digit multiplex drive with hundreds of digits, have a relatively simple structure, and are easy to manufacture. be.

化することは許されない。 Now, a conventional example of a method for manufacturing an MIM portion in a liquid crystal panel using MIM is as follows. FIG. 1 shows an example in which a metal thin film is formed on a glass substrate 1, and the metal is patterned to form a signal electrode 2, an MIM component part 3, and a terminal part 4. A glass substrate or a quartz glass substrate is generally used as the substrate. Examples of materials for metal thin films include tantalum, tantalum nitride,
Examples include aluminum, but basically any metal that can form an oxide insulating film may be used. Methods for forming metal thin films include sputtering, vapor deposition, and the like. Next, the surface of the metal electrode except for the terminal portion 4 is oxidized by an electrochemical method. essentially
Although it is sufficient to oxidize only the surface of the MIM component 3, it is not a problem that the surface of the signal electrode 2 is oxidized. On the other hand, since the terminal portion 4 is for electrical connection with the outside, oxidation of its surface is not allowed.

る。 FIG. 2 shows an example in which an anodic oxidation method is used as the electrochemical method. In FIG. 2, the electrical circuit system is composed of a voltage power source 5, a glass substrate 1, an anodic oxidizing solution 6, and a metal plate 7. In this case, the voltage is applied such that the metal thin film formed on the glass substrate 1 is positive and the metal plate 7 is negative.
Since each metal thin film formed on the glass substrate 1 must be anodized, the terminal portion 4 must be anodized.
It is necessary to electrically connect them together to the positive terminal side of the voltage power source 5 by an appropriate method. Examples of the anodic oxidation solution 6 include citric acid,
Examples include phosphoric acid aqueous solution. Furthermore, an example of the metal plate 7 is a platinum plate. MIM is completed by forming a metal thin film again on the glass substrate 1 on which the metal electrode and oxide insulating film have been formed and patterning it. FIG. 3 shows the appearance of one completed MIM, in which the first formed metal MIM component 3 is intersected by a later formed metal electrode 8.

まつたく同様の方法で組立られる。 Thereafter, the pixel electrode 9 is formed so as to be electrically connected to the metal electrode 8, and thereafter it is assembled in the same manner as a normal liquid crystal panel.

1 is a schematic diagram of a conventional method of manufacturing a part. One problem with this manufacturing method is that when the metal thin film first formed on the insulating substrate is oxidized by an electrochemical method such as anodization, the terminal area is not made into an oxide film, which is conventional. could only be anodized one piece at a time, and it was not possible to anodize continuous panel electrodes on a large glass substrate. This is because the terminal portion 4 in FIG. 1 is for electrical connection with the outside, and oxidation of its surface is not allowed.Although a laboratory manufacturing method is possible, this method does not lead to mass production.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 4 shows the patterning shape of the metal electrode initially formed on the glass substrate 1 in the embodiment of the present invention. The patterning shape shown in FIG. 4 differs from the patterning shown in FIG. 1 in that the panel pattern 12 is continuously provided. The method for attaching an organic thin film on the terminal part 4 of this electrode is OFPR using photolithography.
This figure shows the state in which the organic thin film 10 covering the terminal portion 4 is formed by coating the entire surface → pre-baking at 80° C. for 20 minutes → exposing → developing → post-baking at 120° C. for 20 minutes. FIG. 5 shows the state of anodic oxidation of a continuous pattern in an embodiment of the present invention.
When connected to the organic thin film 10 and anodized, the organic thin film 10
A highly reliable oxide film was formed except for the so-called terminal portion 4. Thereafter, the organic thin film was peeled off with acetone, and the resistivity of the terminal portion 4 did not change before and after the anodization, and the terminal portion 4 was found to have good conductivity without any problem.

Cutting method: By scribing with a tire and cutting after assembling the counter electrode, we were able to make many stable liquid crystal panels at once.

Further, when the insulating film of the non-linear element having the structure of first metal film-insulating film-second metal film is formed by anodizing the first metal, each of the multiple sets of liquid crystal display panels Since the metals are electrically connected, the insulating films of all nonlinear elements can be formed in a single anodic oxidation process, and there is no need to form an insulating film on the connecting terminal made of the first metal film. Since a protective film is provided, an insulating film is not formed on the connection terminal on which the protective film is formed.
