- the conventional board-less method described above can significantly reduce the number of components compared to the TCP method, so that it is possible to reduce mounting material costs and mounting processing costs, and to further improve reliability.
- problems described below there are problems described below.
- the first and third terminals 31a and 33a formed on the TCP are arranged in the y direction, and the take-out direction is the x direction.
- the remaining terminals 31b and 33b are arranged in the X direction, and the extraction direction is the y direction or the ⁇ y direction.
- the number of connection terminals normally required in a display module is about 30 to 60.
- the limit is about 5 terminals that can be arranged in the y direction, such as terminals 31a and 33a (when the connection terminal length is lmm).
- the remaining terminals are all arranged in the X direction as terminals 31b and 33b.
- the electrical connection between the terminal 3 lb and the terminal 33b arranged in the X direction is performed via the panel wiring 27a formed on the display panel.
- the thickness of the conductive film formed on the display panel is less than 1 ⁇ m (generally about several hundred nm), and the sheet resistance is high. Therefore, since the sheet resistance of the wiring formed using the conductive film on the panel is high, connecting the terminal 31b and the terminal 33b using the panel wiring 27a routed on the display panel will result in a connection resistance. Becomes higher. However, since the electrical connection between adjacent TCPs is provided so as to propagate sequentially through the panel wiring 27a, the connection resistance accumulates along the downstream side. For example, when transferring six TCPs When reaching the final TCP, there will be a very high connection resistance of 5 times the connection resistance.
- the wirings 42 formed in the adjacent TCPs 41 are directly connected to each other by the connection unit 43. Since it is not necessary to connect the wirings 42 formed on adjacent TCPs 41 by bowing the panel wiring on the display panel, the resistance value does not increase unlike the connection structure of FIG.
- the connection between wirings 42 formed on adjacent TCP 41 is made by solder connection, and it is difficult to make fine pitch compared with ACF connection, and 60 connections at a pitch of 0.3 mm are assumed. If it does, a total connection area of 18mm is required. Therefore, an increase in the terminal area of the display panel and an increase in cost due to an increase in the TCP area are incurred.
- solder connections must be made individually one by one. For example, when 60 TCPs and 6 TCPs are transferred between adjacent TCPs, the number of connections is 300. Therefore, it takes a lot of time to connect, resulting in an increase in mounting processing costs.
- the wiring network is formed by panel wiring, and further the bypass wiring by FPC84 is used, so that the resistance value increases as in the connection structure of FIG. Unlike the connection structure shown in Fig. 5, the terminal area and mounting processing costs do not increase.
- the panel wirings 81 and 82 cross each other, and in order to cross each other in an insulated state, it is necessary to form a contact hole between the wirings that need to be electrically connected.
- the source side drive IC has 30 or more inputs to the IC, and when 60 inputs and 5 liquid crystal drive ICs are mounted, the number of contact holes formed is 300. . Therefore, the cost increases due to the decrease in the yield of the panel due to the formation of the contact hole.

Therefore, it is an object of the present invention to realize a reduction in module size and light weight, and to provide a display module at a lower cost.
