DESCRIPTION OF THE INVENTION (2) The strip-shaped connecting member 16 used for the upper substrate 1 1 and the strip-shaped connecting member 17 used for the lower substrate 1 2 have the same structure, as shown in Figs. 5 and 6, On one surface of the flexible resin tape 21, a wiring 2 2 having an IC wafer 2 3 'having a conductive film on the other surface is provided. As shown in Fig. 5, the upper substrate 1 1 ' is formed with the surface of the one end portion 16 a of the strip-shaped connecting member 16 of the wiring 2 2 , and then the connecting terminal portion 14 of the inner surface of the upper substrate 1 1 . Upper, and the strip-shaped connecting member 16 is bent into a substantially U-shaped cross section, and the other end portion 16b is formed with the surface of the wiring 2 2 and then the FPC 15 of the outer surface of the upper substrate 1 1 Ends. The portion where the band-shaped connecting member 16 is bent has a slit-like opening 2 1 a in the resin tape 2 1 to make it easy to bend. On the other hand, as for the lower substrate 12, as shown in Fig. 6, the surface of the one end portion 17a of the strip-shaped connecting member 17 having the wiring 2 2 is formed, and then the connecting terminal on the inner side surface of the lower substrate 1 2 is formed. The portion 14 is folded, and the strip-shaped connecting member 17 is bent into a substantially U-shaped cross section, and the other end portion 17b is provided with the surface of the IC wafer 23, and then the outer surface of the upper substrate 1 1 is contacted. The end of the FPC 1 5 on it. The other end portion 1 7 b of the strip-shaped connecting member 17 has a window-like opening 2 1 b on the resin strip 2 1 , and the wiring 2 2 in the opening 2 1 b is in a stripped state. Therefore, welding is performed in this opening 2 1 b, and F P C 1 5 and the strip-shaped connecting member 17 are next connected to connect the wiring 2 2 of the strip-shaped connecting member 17 and the circuit of F P C 15 . [Problems to be Solved by the Invention] However, in such a configuration, the strip-shaped connecting member of the lower substrate 12 is applicable to the Chinese National Standard (CNS) A4 specification (210 X 297 mm) (please read the back first) Note: Please fill out this page again) T ------*-订---------.AV1 Ministry of Economic Affairs Intellectual Property Bureau Staff Consumer Cooperative Print A7 1262345 i£ V. Invention Description (3) The connection portion between the 1 7 and the FPC 1 5 has a problem that peeling easily occurs, or the wiring 2 2 is easily cut. In other words, although the strip-shaped connecting member 17 of the lower substrate 12 has flexibility, it has a certain degree of rigidity in order to dispose the wiring 2 2 and the I C wafer 2 3 and the like. Then, as shown in Fig. 6, when the surface on which the wiring 2 2 is formed is bent outward, that is, when the wiring 2 2 is bent in the direction in which the wiring 2 2 is extended, the wiring 2 2 is retracted as shown in Fig. 5 . When the direction is bent, the stress of the strip-shaped connecting member 17 to be restored to the original state is large. Further, between the wiring 2 2 and the F P C 1 5 of the strip-shaped connecting member 17 of the lower substrate 12, the resin tape 2 is interposed, and the wiring 2 2 and the F P C 1 5 are in close contact with each other. Therefore, in the connection portion between the strip-shaped connecting member 17 and the F P C 1 5, there is a problem that the stress which peels the both acts, and the problem of peeling or disconnection easily occurs. On the other hand, when the strip-shaped connecting member 17 is bent into the structure shown in Fig. 6, the end portion of the connecting terminal portion 14 having the lower substrate 12 is exposed to a small area outside the upper substrate 1 1 . It is possible to make the connection terminal portion 14 and the strip-shaped connecting member 17 follow, but the bent portion of the strip-shaped connecting member 17 greatly protrudes from the edge of the lower substrate 12 and is difficult to handle, and it is necessary to protect the protruding bend. In part, the result is that the device is enlarged and not ideal. Accordingly, an object of the present invention is to prevent the peeling or disconnection of the connection terminal portion of the substrate and the F P C to improve the reliability, improve the usability, and further reduce the size of the device. [Means for Solving the Problem] In order to solve the above problems, the liquid crystal display device of the present invention has a Chinese National Standard (CNS) A4 specification (210 X 297 mm) applied to the paper scale (please read the back sheet first) Fill in this page again) -I -----I -I — 订---I - Ministry of Economic Affairs Intellectual Property Bureau Staff Consumer Cooperative Print A7 1262345 V.
