である。However, in a liquid crystal display device whose mass production is large and its characteristics are frequently improved, if there is no indication of the serial number etc. on the liquid crystal panel, even if a failure occurs in the module state, the manufacturing time or manufacturing conditions of the liquid crystal panel are changed. It was difficult to identify. Therefore, when a problem occurs, the time and man-hours required for the analysis are enormous.
An object of the present invention is to solve the above-mentioned problems and to facilitate the specification of the manufacturing time or manufacturing conditions of a liquid crystal panel.

ことを特徴とする。A liquid crystal display device having a first substrate and a second substrate disposed so as to face the first substrate, wherein an electrode is formed on one surface of the first substrate; A polarizing plate is disposed on the other surface opposite to the surface of the first substrate, a production code is printed on the other surface of the first substrate by ink, and the polarizing plate is provided on the first substrate and the second substrate. The manufacturing code is printed in an area protruding from an area where the first substrate and the second substrate overlap in a plane, wherein the manufacturing code is located in an area where the substrate overlaps in a plane.
以下に具体的な実施例をもって、本発明について説明

プした数字を印字してシリアルナンバーとした。Embodiment 1 FIGS. 1A and 1B show a liquid crystal display device of this embodiment. After attaching the polarizing plate 3 to the position of the surface 4 opposite to the transparent electrode 2 on the transparent substrate 1 made of soda lime glass, the production code of the liquid crystal display device was printed by an ink jet printer. At this time, the ink used was an ultraviolet-curing type ink, and the number counted up for printing on one liquid crystal display device was printed as a serial number.

If a problem occurs, the time and man-hour required for this analysis are greatly reduced. Was done.

とができた。Comparative Example 2 FIGS. 2 (a) and 2 (b) show a liquid crystal display device of this comparative example. When patterning the transparent electrode 2 on the transparent substrate 1 by using the photo method, a laser irradiation device is incorporated in the exposure device, and at the same time as the exposure, a portion of the transparent substrate on the transparent electrode side where there is no transparent electrode is the same as in Example 1. Was printed with the production code. In this case, not only the same effects as in Example 1 can be obtained, but also the process history can be confirmed on the actual product even during the manufacturing process, so that the time and man-hour required for the process analysis can be greatly reduced.

ってしまうことがない。As described above, according to the liquid crystal display device of the present invention, the polarizing plate is disposed on the surface of the substrate opposite to the surface on which the electrodes are formed, and the manufacturing code is printed on the surface, and the polarizing plate is The two substrates are located in an area where the two substrates overlap in a plane, and the production code is printed in an area protruding from the area where the two substrates overlap in a plane. Therefore, since the production code is printed on the surface opposite to the electrode forming surface, the electrodes can be routed irrespective of the position of the production code, so that the degree of freedom in design increases, and the space on the electrode forming surface is also increased. This has the effect that effective utilization can be achieved.
Furthermore, since the polarizing plate does not exist in the region where the manufacturing code is printed, the manufacturing code is not covered with the polarizing plate and becomes invisible.
