FIG. 5 is a diagram showing an example of a connection structure between the liquid crystal display panel 21 and the flexible wiring board 23 of the driving IC 22 according to the present embodiment.
FIG. 6 is a diagram illustrating an arrangement example of the first and second connection portions of the driving IC 22 according to the present embodiment.

The driving IC 22 according to the present embodiment is formed in a so-called rectangular parallelepiped shape in which a plurality of drivers are integrated, and the first connecting portion 221 and the first connecting portion 221 are provided on the connecting portion surface (bottom surface) 22a with a predetermined gap portion 223 therebetween. Two connecting portions 222 are formed.
In addition, it is possible to relieve stress when mounted due to the presence of the gap 223.

  The first connection part 221 is connected to a connection part 21 c formed at (an end part) of the one edge part 21 b of the liquid crystal display panel 21. The first connection part 221 is formed by arranging a plurality of connection terminals 2211 on the side of one edge 22b in the longitudinal direction of the connection part surface 22a of the driving IC 22 (two lines in the example of FIG. 6). .

  The second connection part 222 is connected to the connection part 234 of the flexible wiring board 23. The second connection part 222 is formed by arranging a plurality of connection terminals 2221 in the longitudinal direction of the connection part surface 22a of the driving IC 22 on the other edge part 22c side in one or a plurality of rows (one row in the example of FIG. 6). ing.

Note that the size of the connection terminal 2211 of the first connection portion 221 is about ½ of the connection terminal 2221 of the second connection portion 222.
The connection terminal 2211 and the connection terminal 2221 have the same structure. Specifically, it has a laminated structure of a bump 224 for connection and a gold plating part 225 formed on the bump 224.

The connection portion 21c formed on the one edge portion 21b (the end portion) of the liquid crystal display panel 21 is formed of, for example, ITO or TiAl. Since ITO is used for the pixel electrode and TiAl is also used for the signal wiring or the like, the process of the display pixel region 21a can be applied.
In addition, when TiAl is applied to the wiring portion 21c, Ti (titanium) is resistant to scratches (not easily scratched), which is advantageous from the viewpoint of durability and the like.
Further, since the wiring portion 21c is required to have a low resistance, it is preferable to use a TiAlMo multilayer wiring as shown in FIG. 7, for example. Since Mo (molybdenum) is used for the gate electrode wiring of the bottom gate type TFT, for example, the process of the display pixel region 21a can be applied.

  For example, as shown in FIG. 5, the flexible wiring 23 has a structure in which a conductive layer (for example, Cu) 233 is sandwiched between polyimide layers 231 and 232, and the connection portion 234 has no polyimide layer 231 formed thereon. 233 is exposed.

Further, the second connecting portion 222 of the driving IC 22 and the connecting portion 234 of the flexible wiring board 23 are connected via the flexible wiring board mounting ACF 27.

  The ACFs 26 and 27 are formed by dispersing a large number of conductive particles and insulating particles in an insulating synthetic resin having an adhesive function.

  Thus, in the present embodiment, the driving IC 22 connects the first connection part 221 of the driving IC 22 and the connection part 21c of the liquid crystal display panel 21 using the ACFs 26 and 27, and the driving IC 22 The two connection portions 222 and the connection portion 234 of the flexible wiring board 23 are connected and mounted.

In this mounting, the first connection part 221 of the driving IC 22 is arranged on the liquid crystal display panel 21, and the other region, most of the gap part 223 and the second connection part 222 are located outside the panel.
That is, in this embodiment, the flexible wiring board 23 is not mounted on the liquid crystal display panel 21, but is mounted directly on the driving IC 22.

In other words, a driving IC 22 is mounted on the surface of the liquid crystal display panel 21 for the digital interface of the liquid crystal display device, and various power supplies, ground lines, and signals necessary for operating the liquid crystal display panel 21 are extracted from the flexible wiring board 23. Used for.
Regarding the mounting of each component member, the IC is mounted on the liquid crystal display panel surface and the flexible wiring board 23 is mounted on the driving IC 22 by pressure bonding with ACFs (binders) 26 and 27 each containing conductive particles. Let it form.

With this structure, in a general liquid crystal display device, the width of the driving IC, the width of the flexible wiring mounting portion, and the frame limited by the respective clearances are limited only by the width of the driving IC 22. Realize a narrow frame and increase product value.
In particular, in FIG. 8, as shown by comparing the general liquid crystal display device (FIG. 1) 10 and the liquid crystal display device 20 according to the first embodiment, the connection wiring between the IC 22 and the flexible wiring 25 is a liquid crystal. There is no need to form it on the display panel, and there is an advantage that not only the frame can be downsized but also the yield of the liquid crystal display panel can be improved.

  In the past, when mounting the driving IC 22 and the like on the liquid crystal display panel 21 using the ACF, the size of the glass substrate 211 of the liquid crystal display panel 21 depends on the size of the ACF. Depending on the structure, the ACF can be freely sized, so the size of the glass substrate can also be selected without depending on the ACF size, and further can be realized.

  Up to now, the ACF width of about 1.5 mm to 3 mm has been adopted. However, according to this embodiment, a width of about 0.5 mm to 1.2 mm can be adopted, and further narrowing the frame. Will contribute.

<Second Embodiment>
FIG. 9 is a front view showing a configuration example of a liquid crystal display device according to the second embodiment of the present invention.

  The liquid crystal display device 20A of the second embodiment is different from the liquid crystal display device 20 of the first embodiment in that the driving IC is downsized.

As described above, with the narrowing of the frame, the liquid crystal display panel wiring resistance from the driving IC 22A to the flexible wiring board 24 and the mounting resistance of the flexible wiring board 23 and the liquid crystal display panel 21 can be reduced.
For this reason, when the minimum resistance value necessary for driving is comprehensively considered, the connection resistance between the driving IC 22A and the liquid crystal display panel 21 may be slightly increased, and the bump area which is the connection terminal of the IC is reduced. If the pattern area of the liquid crystal display device is reduced, the driving IC 22A can be reduced in size.
As a result, it is possible to improve the yield of the driving IC and to reduce the price, and the frame can be further reduced in size as compared with FIG. 3 of the first embodiment.

The presence of the protection unit 30 protects the connection region between the second connection unit 222 of the IC 22 where the liquid crystal display panel 21 is exposed to the connection unit 234 of the flexible wiring board 23, and causes a large bend in the region. And can keep the connection state stable.
Further, the outer surface 32 of the protection unit 30 and the side surface 22d of the driving IC 22 are substantially the same distance from the side surface of the glass substrate 211. In other words, the outer surface 32 of the protection unit 30 is connected to the side surface 22d of the driving IC 22. By forming them so as to be substantially in the same position (on the same line), it is possible to prevent widening of the frame while maintaining the function with the protection unit 30.

  According to the third embodiment, as shown in FIG. 11, a general liquid crystal display device (FIG. 1) 10 and the liquid crystal display device 20B according to the third embodiment are compared and shown in FIG. There is no need to form the connection wiring between the wirings 23 on the liquid crystal display panel, and there is an advantage that not only the frame can be downsized but also the yield of the liquid crystal display panel can be improved.

There is no need to form the connection wiring between the wirings 23 on the liquid crystal display panel, and there is an advantage that not only the frame can be downsized but also the yield of the liquid crystal display panel can be improved.
In this case, the UV curable resin is applied to the application portion 41 between the side surface 22e of the driving IC 22 and the liquid crystal display panel 21, and the IC 22 where the side surface of the glass substrate 211 and the crystal display panel 21 are exposed to the outside. In the case of the general liquid crystal display device 10C, two places of the application portion 42 that forms a support portion 40 that protects and supports the connection region of the second connection portion 222 with the connection portion 234 of the flexible wiring board 23 It becomes possible to reduce from three places.
