The length of the scan electrode terminal 124R in the lower layer display panel 111R is longer than LR! /.
- the scanning driver terminal 132 is joined to the scanning electrode terminal 124R of the lower layer instead of the scanning electrode terminal 124B of the upper layer, the length LB of the scanning electrode terminal 124B of the upper layer and the scanning electrode of the lower layer are combined. Reverse the length LR of terminal 124R.
- FIG. 13, FIG. 14 (A, B), 015 (A, B) and FIG. 16 (A, B) show the three-layer type, four-layer type, five-layer type, and six-layer type display panel 101, respectively. It is explanatory drawing of the manufacturing method of the display apparatus 101 provided with. Figure 17 shows the flow of these manufacturing methods.
- a display panel 111 is prepared so that the length of the scan electrode terminal 124 becomes longer in the order of “intermediate layer, lower layer, upper layer” (FIG. 17, S 10),
- the scanning electrode terminals 124 of the display panels 111 are joined together in numerical order (FIG. 17, S30), and finally the terminals of the driving driver 132 are joined (FIG. 17, S50).
- the scan electrode substrate 126 of the display panel 111 can be bent because it is a flexible substrate.
- step S30 the scan electrode terminal 124 of the middle-layer display panel 111 is joined to the scan electrode terminal 124 of the lower-layer, upper-layer, or other middle-layer display panel 111.
- the scan electrode terminal 124 of the lower layer display panel 111 is joined to the scan electrode terminal 124 of the upper layer display panel 111 (S30-2).
