法として、一般にこの実装部の形状が用いられている。[Prior art] The color filter thX M= plate is the 37th plate consisting of the N live pattern of the three primary colors of RGB as shown in Fig. 2.
As shown in FIG. 2, a general configuration has 14 mounting portions for moving the liquid crystal panel on the upper and lower sides. An enlarged view of this mounting part is shown in Section 5. The mounting terminals are drawn out vertically in one linear order, and the mounting terminals of each RGB color are alternately distributed vertically. Normally, in a panel with a diagonal of 10 inches, the electrode pattern pitch is 0.12 to ○, ', 3.
However, since it is difficult to perform TAB mounting of ICs with a pitch of 0.2 mm or less, this mounting part shape is generally used as a method of increasing the pitch interval.

ＩＣが実装できないなどのデメリットがあった。However, when a color filter is produced by micelle electrolysis using the conventional pattern shown in Figure 6, the first color can be formed in one step through the outermost conductive part (Figure 6-5), but the second color and The third color requires at least five electrolysis steps and requires a minimum of 5 man-hours to form a film after connecting the two-color giant and third-color film formation lead wires located above and below (Fig. 6-10゜11). However, there was a problem in that the yield was lowered. In other words, in the micelle electrolysis method, when conducting the second or third color film formation line, it is an easy energization method that does not require selective energization, which is troublesome in terms of production technology. If you use the method of simultaneously making the lines of This is because a pigment film of a second or third color is formed on top of the pigment film of the previous color, resulting in color mixing. On the other hand, although there are some methods of film formation that do not cause color mixing, they have disadvantages such as complicating the process and not being able to directly mount a liquid crystal driving IC on the electrode designed for film formation.
［発明が解決しようとする課題］ 従来のミセル電解法に用いる電極基板では。[Problem to be solved by the invention] In the electrode substrate used in conventional micelle electrolysis method.

していた。The first color can be formed in one step through the outermost conductive part (Fig. 6-5), but the second and third colors are located above and below, respectively.
Since the film is formed after the second and third color film formation lead wires are electrically connected (Fig. 6-Lo, 11), at least 5 electrolysis is required, which requires a large number of man-hours and reduces the yield. There was a problem. In addition, with this method, when connecting the film forming terminals of the second color or C or third color, the lines of the first or second color are also connected at the same time (Figure 6-9, 10).
Therefore, if the first or second color pigment film has conductivity, the second or third color pigment film will be formed on top of the first or second color pigment film, causing the color to change. This had a major problem in that colors were mixed, and countermeasures against color mixing were required.

The objective is to provide an electrode pattern that can be used.

、 ことを特徴とするカラーフィルター用電極基板。(1) In an electrode substrate for a color filter consisting of a striped pattern of three primary colors RGB, an electrode pattern for forming the color filter by wet film formation is formed on the substrate, and the electrode pattern is formed by wet film formation. (Fig. 1-7), the terminal part for mounting the LCD driving IC (Fig. 1-6), and the part where wet film formation is performed, that is, the color filter part (Fig. 1-1, 2, 3). ), [1] 1st color [1, 4, 7 from the left end... (3n-2)
line (Fig. 1-1)] is 1
Lines are drawn out alternately up and down (from the left 1, 7,
13th...(6n-5)th is top, 4th, 10th, 16th...
・The (6n-2)th line is on the bottom or vice versa) and is connected to the conductive line (Fig. 1-5) formed on the outermost periphery of the substrate, and a part of the lead line is connected to the liquid crystal drive line. Commonly used as the IC mounting terminal (Fig. 1-6), [2] 2
The film formation leader lines of the colors [2nd, 5th, 8th...(3n-1)th lines from the left end (Figure 1-2)] are all opposite to the first film formation leader line from the left end. It is pulled out to the side, and the terminal part for mounting the LCD drive IC is 5 from the left.
, 11, 17...(6n-1)th lines are placed on the opposite side from the film forming lead line, and 2nd, 8th, 14th...(6n-4)th lines from the left For the line, use a part of the film forming lead line, and [3] draw out the film forming drawer for the third color [3rd, 6th, 9th...3nth line from the left end (Figure 1-3)]. Line (Figure 1-9)
are all drawn out in the same direction as the first film-forming lead line from the left end, and the 6th, 12th, 18th... For the 3rd, 9th, 15th... (6n-3)th line from the left, a part of the film forming lead line is used. An electrode substrate for a color filter characterized by the following.
