- the alignment marks 73a, 73b, 74a, 74b provided on the central axes of the respective planar substrates 51a, 52a cause the respective planar substrates 51a , 52a, the position in the long side direction, the position in the short side direction, and the rotation position can be appropriately adjusted.
- the sides of the flat boards 51a and 52a on the side where the second areas 71a, 71b, 72a and 72b are provided are common.
- the length of the side in the direction perpendicular to the length is different for each size.
- the length of one side of the planar substrate differs depending on the size of the substrate, but the portion for performing processing such as support and alignment mainly includes the end portion of the substrate including the second region having the common side length. Therefore, as in the other embodiments described above, the manufacturing equipment can be shared.
- FIG. 16A After the two flat substrates 51a and 52a are sealed by the above-described method, as shown in FIG. 2. Cut and separate the region 30a. Then, sharp cutting corners 80a, 80b, 80c, and 80d appear. It is desirable to chamfer such an advantageous cut corner from the viewpoints of safety and durability of a flexible wiring to be mounted in a mounting area. However, the corner 80c located on the sealing surface side is located at a position where chamfering is difficult.
- the corner 80 c is not chamfered. Even if chamfering is not performed, the corners 80c are difficult to access from the outside, and are locations that cannot reach the flexible wiring board. .
- FIGS. 17 and 18 may be used as another processing method of the sharp cutting corner. That is, the embodiment shown in FIG. 17 has a configuration in which the corner 80 c that is difficult to perform chamfering is covered with the protective material 90. Thus, it is possible to prevent the corner portion 80c from coming into contact with the outside.
- the protective material 90 a resin, an adhesive, a putty, a tape, or the like is used.
- the protective material 90 is also configured to also seal the adhesive surface 101 of the flexible wiring board 100.
- the flexible wiring board 100 is bonded to the substrate by heating and pressing through an anisotropic conductive film.
- the bonding portion that bears the withstand voltage between the wirings arranged at a narrow pitch 1 0 1 Is weak to moisture and foreign matter from the outside, and a force is applied when bending the flexible wiring 100.
- the protective material 90 can not only cover the sharp corners but also serve to protect the adhesive surface 101 of the flexible wiring board 100, which is effective. Become.
- the method of manufacturing the flat substrate itself is the same as that of the above-described embodiment, and a detailed description thereof will be omitted.
- the present invention is not limited to the above-described embodiment, and can be variously modified within the scope of the present invention.
- the description has been given of the case where the FED is manufactured.
- the present invention is not limited to the FED, and can be applied to the manufacture of another flat display device such as an SED and a PDP.
- the dimensions of the planar substrate to be used, the dimensions and the number of the first regions to be formed, and the like are not limited to the above-described embodiment, and can be selected as necessary.
- the size of the flat substrate in the manufacturing process is set to a large common size, and unnecessary regions of the flat substrate are finally cut and separated, thereby achieving the common substrate and the common manufacturing process.
- a flat display device having a different size can be manufactured. Further, according to an aspect of the present invention, it is possible to provide a method of manufacturing a flat display device capable of reducing interference of a manufacturing facility on a manufacturing process and narrowing a frame of the flat display device.
