Abstract

PROBLEM TO BE SOLVED: To prevent the gap defect of injection ports and to make the suction rate of a sealant quantitative by providing black masks, color filters and transparent electrodes with dummy parts to be respectively arranged in the positions of the injection ports. SOLUTION: Common ITO 6 and ITO dummies 5 respectively have extended parts 5B which respectively exist in the injection ports 7A thereof and are extended in a longitudinal direction. These extended parts 5B exist exactly in the parts of the injection ports 7A. Further, freshly formed color filter dummies 4A,... exist in the parts of the injection ports 7A. Further, black mask dummy parts 2A exist exactly in the parts of the injection ports 7A. The additional parts (5B, 5B, 4A, 2A) respectively existing in the parts of the injection ports 7A are added to the respective members (6, 5, 4, 2) in such a manner and, therefore, the film structures of the peripheries of the display section and the injection ports 7A are the same and have no differences in level in the injection ports 7A. The gap defect is thus prevented.

2. Description of the Related Art A conventional color liquid crystal display will be briefly described with reference to FIGS. FIG. 3 is an explanatory plan view perspective view of the display, and FIG. 3 is an exploded perspective view thereof. In particular, FIG.
As can be understood from FIG. 1, the structure of the color filter 3 generally used for a liquid crystal display is, for example, red,
The green and blue patterns are formed. Further, for the purpose of improving the contrast, a black mask 2 such as a black paste is patterned on the gap between the patterns and the frame of the display section. These red,
There are steps on the green and blue patterns due to the film thickness of each pattern. In order to flatten this step, a transparent resin such as acrylic is applied on the pattern to form an overcoat layer, and a transparent common transparent electrode (common ITO) 6 is formed thereon. . The substrate thus configured is the first substrate FS of the color filter. A second substrate SS having a transparent electrode (segment ITO) 9 formed on a glass substrate 1A is opposed to the first substrate (color filter substrate) FS. That is, the second substrate SS is bonded to the first substrate FS with a spacer (not shown) sandwiched therebetween by a bonding material (hereinafter referred to as a seal) 7, and the first and second substrates FS, SS A liquid crystal (not shown) is injected and sealed into the gap, thereby forming a liquid crystal display LCD. In addition, a seal piece 7B in the form of dotted seals is formed in an injection port 7A described later.

In order to make the liquid crystal display more easily visible by using the above-mentioned color filter substrate (FS), a black paste or the like is used as the black mask 2, and the frame portion thereof is more intense. In many cases, a solid black mask having good light shielding properties is used, and the entire outer periphery of the display portion of the liquid crystal display LCD is formed as a black mask. In this case, the edge of the black mask is often formed up to the sealing position so that light leakage does not occur on the outer periphery of the display unit. When the upper side of the black mask on the outer periphery of the display unit is viewed, the color filter dummy 4 and the transparent electrode dummy ( I
(TO dummy) 5 may be formed. However, an opening portion for injecting liquid crystal (hereinafter referred to as an injection port) 7A.
When sealing is performed with a sealing material, it is difficult to control the gap in the portion of the injection port 7A, and the gap becomes nonuniform, which causes a failure. In addition, due to such non-uniformity of the gap, it is difficult to control the suction amount of the sealing material, and insufficient suction or excessive suction has occurred.

DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 is a perspective view of each member (membrane) of an embodiment of the present invention separated for explanation, and FIG. Reference numerals 2 respectively correspond to FIGS. In FIGS. 1 and 2, members equivalent to those in FIGS. 3 and 4 are denoted by the same reference numerals and description thereof is omitted, and portions different from FIGS. The liquid crystal display LCD of FIG. 1 has a first substrate FS and a second substrate SS aligned with a seal 7. The black mask 2 is formed so as not to overlap the seal 7. Further, for comparison, FIG.
The ITO dummy 5 as a dummy of the TO 6, the color filter dummy 4 as a dummy of the color filter 3, and the black mask 2 are all formed up to a substantially frame-shaped seal 7. Conventionally, since the pattern of the members (5, 4, 2) has not been considered deeply, if the injection port 7A is assumed to be a virtual virtual seal line extending the outer circumference of both ends where the seal 7 is cut, it can be understood from FIG. The above member (5,
4, 2) were located inside the assumed seal line. As described above, since each of the members (5, 4, 2) is located inside the virtual seal line 7B, these members (5, 4, 2) are present at the inlet 7A. do not do. On the other hand, since these members (5, 4, 2) are present in the immediate vicinity, a step is generated between them, and a gap defect has occurred at the injection port 7A. The reason is that the seal 7 and the seal piece 7C are formed at the same time. At this time, the member (5, 4, 2) exists at the seal 7 portion, whereas the member (5, It is considered that (5, 4, 2) does not exist.

More specifically, as can be seen from FIG. 1, the injection port 7 of the common ITO 6 and the ITO dummy 5 is formed.
It is assumed that each of the portions located at the portion A has an extended portion 5B extending in the longitudinal direction. The extended portion 5B is positioned exactly at the inlet 7A.
Further, regarding the color filter dummy 4, another color filter dummy 4A, 4A,... Is newly formed. This new color filter dummy 4A, 4A,... Is located at the injection port 7A. Further, regarding the black mask 2, a black mask dummy portion 2A is extended to a part thereof corresponding to the injection port 7A.
