Are bonded together with a frame-shaped seal member provided between them at a constant interval, and a liquid crystal material is sealed inside thereof, and a large number of them are laterally arranged on the inner surface of the upper substrate b. Common electrodes (or signal electrodes) are arrayed and formed, and a large number of signal electrodes (or common electrodes) are vertically formed on the inner surface of the lower substrate c. The lead portions of the common electrode and the signal electrode are extended to the outside across the sealing member, and the common electrode is formed on the lower surface of the connection portion d extending on the side surface of the upper substrate b, for example. (Or signal electrode) lead terminals are connected to form an array of electrode terminals,
In addition, electrode terminals to which the lead portions of the signal electrodes (or common electrodes) are connected are formed in an array on the upper surface of the connection portion e extending on the side surface of the lower substrate c. By the way, when a plurality of such liquid crystal display panels a are arranged adjacent to each other on the same surface to increase the screen size, conventionally, as shown in FIG. Since the extended connecting portions d and d are arranged so as to abut each other on the same surface, the joint width for connecting the connecting portions d and d is wide. However, since the connection portions d and d and the gaps between the connection portions d and d are non-image portions, a wide non-image portion α is formed in the screen,
There was an inconvenience that the image became difficult to see. Further, in order to connect the electrode terminals of the adjacent liquid crystal display panels between the connection parts d of the adjacent liquid crystal display panels, a connecting means f such as a film connector is provided between the connection parts d, d.
It is necessary to interpose the connection parts d, d
The gap between them cannot be made small, which has been a restriction in narrowing the non-image portion α described above.
