題点が、上記従来の検査方法にはあった。However, the conventional inspection method described above has the following problems. That is, in a normal liquid crystal display element, as shown in FIG. 2, an alignment film 4 is provided on the display electrode 3. For this reason, the above-mentioned conventional inspection method has a problem in that it becomes difficult to visually observe the pattern on the lower side, making inspection difficult.

法を提供するものである。<Purpose/Structure of the Invention> [Non-explosion] was made with the aim of solving the above-mentioned problems in the conventional inspection method, and in order to achieve this purpose, a In addition to providing a conductive substrate bonding accuracy test pattern, a means for applying a lighting voltage between the patterns from the outside of the liquid crystal display element is provided, and whether the lighting or non-lighting occurs when the lighting voltage is applied between the patterns is provided. The present invention provides a method for inspecting the bonding accuracy of substrates, which is characterized in that the lighting state is checked, and the bonding accuracy of the two electrode substrates is inspected.
〈実施例〉

を示す図である。<Example> FIG. 3 shows that in the present invention, the same electrode forming material as above is applied on the surface of one electrode substrate (common electrode substrate) (on the surface on which the transparent electrode for display is formed). A pattern 11 for inspecting the accuracy of substrate bonding formed with f='1 and a pattern 11 for inspecting the accuracy of substrate bonding 9 formed in the same manner on the surface of the other electrode substrate (segment electrode substrate). It is a figure showing I2.
上記両パターンは、基板貼り合わせが許容誤差範囲内で

接続された構成となっている点にある。Both patterns are provided in such a positional relationship that they do not overlap when the substrates are bonded together within an allowable error range. A feature of the present invention is that the patterns 11 and 12 are electrically connected to the common electrode terminal and the segment electrode terminal, respectively, by appropriate connection patterns.
このような構成とすることにより、液晶表示素子完成後

パターンが重なり合う部分（図の斜線部）が生じるので
、この部分が点灯状態となる。With this configuration, an appropriate lighting voltage can be applied between the two patterns after the liquid crystal display element is completed. When the substrates are bonded together within the allowable error range, as shown in FIG. 3, the two double patterns do not overlap, so no dots occur. On the other hand, if the substrate bonding error exceeds the specified value, as shown in FIG. 4, there will be a portion where both patterns overlap (the shaded portion in the figure), and this portion will be lit.

としこなるものである。Therefore, if lighting is observed when an appropriate lighting voltage is applied between the above two patterns, it means that the liquid crystal display element has a substrate bonding error that is greater than the specified value. If this is not observed, it can be said that the error in bonding the substrates of the liquid crystal display element is within the specified range.
上記実施例に於ては、各基板貼り合わせ精度検査用パタ
