Abstract

PURPOSE:To obtain easily mountable liquid crystal display device through arrangement, in the form of matrix, of the nonlinear elements having the structure of metal-insulator-metal by depositing organic substance layer to unnecessary area and then selectively anode-oxidizing them. CONSTITUTION:A patterned metal layer 7 on the first layer of glass substrate 8 is selectively covered with a resist 9 and the anode oxide film is formed in the electrolyte as specified. The portion masked by resist 9 becomes a terminal at the time of assembling. The resist 9 is removed and the glass substrate 8 is cut along the dotted line. Thereby, a substrate on which the terminal 11 exists in the right and left in one after another line cab be obtained. According to this structure, terminal interval can be widened even when integration density of metal- insulator-metal structure becmoes high, and moreover when a liquid crystal display device is assembled by forming the glass substrate 8 in the form of matrix, such a device can be mounted very easily.

Description

[Detailed description of the invention] The non-invention is metal insulator metal (hereinafter referred to as M)
The present invention relates to an anodizing method during the manufacturing process of a glass substrate in which IM) is arranged in a matrix on a glass substrate.

Conventionally, the first metal layer of the MIM was patterned into the shape shown in FIG. 1, and then anodized to form a part of the insulator. In the patterning shape shown in FIG. 1111, as shown in FIG. 112, the line 1 consisting of the terminal portion 3 and the wiring portion 4 to the MIM is formed on the glass 1 plate 2 [1#! I array n
et's. After buttering into the shape shown in Fig. 1, as shown in Fig. w45, the patterning of *a is
Metal line 1 on the 91st layer? , after making all the conductive AI with the conductive rubber 5, enter the electrolysis 96 to the wiring part 4 to the M engineering M,
*Anodic oxidation is performed on the first metal line 1 that has been buttered at the same time.

In the anodic oxidation method like Jin, as the integration density of MIM increases, the interval between the metal lines 1 in the first layer becomes narrower, and the MIM
When assembling a shoreline display AM using a glass plate 2 on which IMs are arranged in a matrix, there is a drawback that mounting is difficult.

In addition, there was a drawback in that the area of entry into the electrolyte 6 had to be adjusted so that the Kameko WA 5 would not be anodic oxidized.

Furthermore, if the electrolytic solution 6 ripples during anodization, there is a drawback that the terminal portion 3't will be anodized.

In addition, all the first metal lines 1 on the load must be made conductive and anodized at the same time, and this rounding,
When the conductive rubber 5f was used, there was a drawback that the conductive rubber 5 was contaminated with dirt, which deteriorated the characteristics of MXM.

The present invention eliminates such drawbacks and aims to provide an anodizing method 11 for manufacturing a glass substrate in which M:[M is arranged in a matrix, which is easy to implement.

Hereinafter, the invention will be described in detail based on examples.

FIG. 141 shows the shape of the first metal layer of the MIM when anodized according to the present invention. 7 is the turned first layer metal, 8Fi glass substrate, and 9 is a resist. Figure 5 shows the patterning of each MIM attached to the glass substrate B shown in Figure 1J44.The part of the metal 7 that is not in the electrolyte 6 is held between clips and connected to the anode of a DC power supply. do. Connect platinum to the cathode of the DC power source and put it into the electrolyte f116. By applying a predetermined voltage between the anode and cathode of the DC power supply, the patterned first layer metal 70 contained in the electrolytic solution 6 is anodized. Here, a resist 9 made of an organic material is applied to the portions indicated by diagonal details. The metal in the portion covered by the resist 9 is not anodized. The portions that are not anodized by the resist 9 are portions that will become terminal portions when assembled into the liquid crystal display device 1.

After the glass substrate shown in FIG. 4 is anodized, the resist 9f is peeled off and the glass substrate 8f is marked with the dotted line shown in FIG.
When cut, a board as shown in FIG. 6 is obtained in which terminal portions are present on the left and right sides in one line.

The shaded area 10 in FIG. 6 is the patterning of the first layer of MIM -n7? : Anodized parts of the metal, and 11 are the left and right KWI shingles on every other line.

According to the present invention, fL can widen the interval between terminals even if the integration density of MXM increases, and by using the glass substrate 8 on which MIMs are arranged in a matrix, W11
#1 When assembled, display device IIf has the advantage of being easy to mount.

In addition, when anodizing, the electrolyte is poured into 6 areas, and the 4th
Set the liquid level so that it reaches the threshold indicated by arrow 12 in the figure.
It has the advantage of mass production KTI.

Another advantage is that even if the electrolytic solution 6 is somewhat rippled during anodization, there is no effect.

As explained above, this invention
Accordingly, it is possible to provide an optimal liquid crystal display device in which non-silent elements are arranged in a matrix.
