[0113] In recent years, along with the development of microfabrication technology, the wiring pitch has also been significantly narrowed. Along with this, high-precision joining is required. However, a certain degree of variation in the manufacturing stage must also be taken into consideration, and it is generally necessary to design the wiring pitch and the like in consideration of the variation in the manufacturing stage. That is, it is necessary to design the wiring pitch with a certain degree of safety factor.
[0114] In the second embodiment of the present invention, an alignment correction method that enables highly accurate bonding even when the wiring pitch is further reduced will be described.
[0115] Figure 10 It is a figure explaining the alignment correction of 2nd Embodiment of this invention.
[0116] Here, a case where the lower electrode on the TCP side is joined to the upper electrode on the array substrate (glass substrate) side will be described. For ...
