本発明は、ガラス等の基板上に印刷方式等により着色皮

置の電気光学表示装置用カラーフィルターの製造方法。DETAILED DESCRIPTION OF THE INVENTION [Industrial Field of Application] In the present invention, a colored film is formed on a substrate such as glass by a printing method or the like. A method for manufacturing color filters for electro-optic display devices such as liquid crystal displays and other precision electronic devices.
カラーフィルターの製造方法には、フォトリソ法電着法
、印刷法、等であるが、いずれの方法でもR−G−B、
三色のパターン位置を出す為に、第4図に示す様な十字
トンボを、アライナ−′マークとして使用し、カラーフ
ィルターの製造を行うのが通常であった。Color filter manufacturing methods include photolithography, electrodeposition, printing, etc., but any of these methods can produce R-G-B, R-G-B,
In order to indicate the positions of the three-color patterns, it has been common practice to use cross-shaped registration marks as shown in FIG. 4 as aligner marks to manufacture color filters.
ところで画像形成に於いては、R−G−Bの三色を同一
基板上に、例えば3回で印刷を行う場合、それぞれ各色

精度にμm単位を要求される今日、必ずしも充分と、云
えず位置合わせ不良によるR−GφBのパターン11の
不均一や、各画素間に隙が生じ点灯時の光モレによる色
調不良を起こし易い問題点を有していた。By the way, in image formation, when printing three colors of R, G, and B on the same substrate, for example, three times, the positional accuracy of each color is important, and the accuracy requires micrometer units. do. However, in today's world where positional accuracy is required in micrometer units, the conventional method using cross-shaped registration marks is not always sufficient, resulting in non-uniformity of the R-GφB pattern 11 due to poor alignment, and gaps between each pixel that occur during lighting. This had the problem of easily causing poor color tone due to light leakage.
そこで本発明は従来の、この様な問題点を解決するもの
で、その目的とする所は、均一なパターン幅で画素間に
隙の無いカラーフィルターを提供するところにある。The present invention is intended to solve these conventional problems, and its purpose is to provide a color filter that has a uniform pattern width and no gaps between pixels.
本発明は上記の問題点を解決する為に、印刷方式等によ
り基板上に所定のパターンの形成を行う場合にRGBの
位置合わせで、アライナ−マークとして円又は多角形の
独立形状を複数連続して用いた事を特徴とする。In order to solve the above problems, the present invention uses a plurality of consecutive circular or polygonal independent shapes as aligner marks for RGB alignment when forming a predetermined pattern on a substrate using a printing method or the like. It is characterized by its use.
本発明では従来のアライナ−マークの代わりに、円又は
多角形(例えば三角形)等の形状を使用する。従来のア
ライナ−マークの使用では、第5図に示す如く、1色目
と2色目がズした場合白黒モニターテレビに映るトンボ
は、数μm程度の、ズレでは1色目も2色目も同じ黒色
に映る為、ズレが判別できないという問題点が生じた。The present invention uses shapes such as circles or polygons (eg, triangles) in place of traditional aligner marks. When using conventional aligner marks, as shown in Figure 5, if the first and second colors are misaligned, the registration marks shown on a black-and-white monitor TV will appear the same black if the misalignment is only a few micrometers. Therefore, a problem arose in that the deviation could not be determined.
そこで第1図に示す通り、φ130μmと、径130μ
mの三角形アライナ−マークを使用したところ、第2図
、第3図に示すとおり、ズして重なった場合でも、又離
れた場合でも、映る色調の、いかんにかかわらず、ハツ
キリ判別できる為、位置を完全に合わせる事ができ結果
として、ズレは生じず三色とも同じパターン巾で画素間
に隙の無いカラーフィルターを製造する事ができ点灯時
の光モレによる色調不良が解決された。Therefore, as shown in Figure 1, the diameter is 130μm and the diameter is 130μm.
When using the m triangular aligner mark, as shown in Figures 2 and 3, even if they overlap or are separated, it is possible to clearly distinguish the colors regardless of the reflected color tone. As a result, we were able to perfectly align the positions, and as a result, we were able to manufacture a color filter with the same pattern width for all three colors without any gaps between pixels, and the color tone defects caused by light leakage during lighting were resolved.

テレビにて確認後、Gを印刷し、同様にBも印刷した。The aligner mark is φ130, the same size as the pattern width.
Figure 1 shows a diameter of μm, and a circular one was used. This is made to have the same size for the purpose of accurately moving by one pixel. The ink used was Toyo Ink's RGB three-color ink for waterless lithographic printing, and the printing pressure was 0.111 mm. R was first printed and dried. Next, adjust the print position by one aligner mark.
After making a trial print with a shift of 30 μm and confirming on a monitor TV that the outer circumferences of the circles of the aligner marks were in contact with each other and there were no overlaps and no gaps, G was printed, and B was also printed in the same manner.

Printed at m±3μm, and the printing position is also the reference position ±3μm.
It was in the. If the reference position size is not within ±10 μm, there will be a misalignment with the ITO electrode, and the light transmission area will be narrowed, making it impossible to obtain good image quality. Good results were obtained, with no gaps between pixels and no poor color tone due to light leakage in the lighting results.
