Description

  The present invention relates to a display device, and more particularly to a connection structure between a driver IC and a transmission wiring in the display device.

  In recent years, with the full-scale advancement of an advanced video and information society and the rapid spread of multimedia systems, the importance of liquid crystal display devices that play a leading role in flat panel displays is increasing. The liquid crystal display device was born from the liquid crystal discovered by F. Reinizer in 1888 and the thin film transistor invented by P. Weimer in 1961, and its development and application development continue to progress. In addition, the needs for liquid crystal display devices are continually diversifying and expanding, and expectations are growing for new possibilities.

  There are two types of driving methods for liquid crystal display devices, segment electrode driving and matrix electrode driving, depending on the difference in electrode configuration for applying a voltage to the liquid crystal. The latter is classified into passive matrix driving and active matrix driving due to the difference in the electric addressing method. In the passive matrix driving, the intersection of the scanning electrode and the signal electrode corresponds to the pixel, and the driving signal is directly applied. Typically, the scan electrode and the signal electrode are formed on separate glass substrates, crossed over each other, and a liquid crystal is sandwiched therebetween.

  Hereinafter, a passive matrix liquid crystal display device will be described as an example. In a TN (Twisted Nematic) mode of a conventional liquid crystal display device, nematic liquid crystal having a positive dielectric anisotropy is formed between two electrode substrates on which a transparent electrode made of ITO is formed so as to have a 90-degree spiral structure. It was sealed between the substrates, and a polarizing plate was disposed outside the substrates. The liquid crystal display device having such a twist angle has problems such as viewing angle characteristics and the limit of the number of time divisions.

  However, in Apll. Phys. Lett., 45,1021 (1984), a liquid crystal display in STN (Super Twisted Nematic) mode that increases the number of time divisions by making the twist angle larger than 180 degrees and utilizing the birefringence effect. A device was proposed. The STN mode liquid crystal display device includes a pair of substrates disposed to face each other with a liquid crystal layer interposed therebetween. The electrodes that form the display region on the side of the pair of substrates that are in contact with the liquid crystal layer are arranged at a higher density than the arrangement density of the electrodes from the display region and are connected to the lead-out wiring drawn out to the periphery of the substrate . The routing wiring is connected to the drive circuit. As one method for connecting drive circuits, a chip-on-glass (COG) system is proposed in which a drive circuit is directly mounted on one peripheral surface of a pair of substrates. COG is a preferable drive circuit mounting form from the viewpoint of reducing the number of members and reducing the panel size.

  Here, Patent Document 1 discloses reduction of the panel size by reducing the size of the peripheral area outside the display area. Specifically, both the scanning electrode driving circuit and the signal electrode driving circuit are provided on one side of the upper side of the panel, and the electrode and the driving circuit are connected to each other through a wiring. Further, a part of the routing wiring is connected to routing wiring of different layers through contact holes, and has a multilayer wiring structure of two or more layers arranged so as to overlap with other routing wiring via an interlayer insulating film.

  As a result, the routing wiring connected to the scanning electrode wiring and the signal electrode wiring is routed around the image display portion on the substrate, and the scanning electrode side terminal and the signal electrode side terminal are juxtaposed on one side of the substrate. Can be reduced. In addition, since a part of the routing wiring is converted into routing wiring of different layers through a contact hole, and a multi-layer structure of two or more layers arranged so as to overlap with other routing wiring via an interlayer insulating film, Furthermore, the area occupied by the routing wiring portion can be reduced.

  FIG. 4 schematically shows an outline of the wiring structure of the liquid crystal display device 40 using the prior art. 41a is a front side transparent substrate made of glass or the like, and 41b is a back side transparent substrate made of glass or the like. Between the front side transparent substrate 41a and the back side transparent substrate 41b, a display region 42 for displaying an image composed of a plurality of pixels is formed. A seal portion 43 is formed on the outer periphery of the display area 42. The seal portion 43 fixes the front transparent substrate 41a and the rear transparent substrate 41b, and seals the display area 42 in the sealing space. In the sealed space, STN mode liquid crystal is sealed.

  In the display area 42, a plurality of X electrode wirings 411 and a plurality of Y electrode wirings 412 are formed, and the intersection of each X electrode wiring 411 and each Y electrode wiring 412 constitutes one pixel. A driver IC 44 is mounted on the rear transparent substrate 41b by the COG method. An X electrode routing wiring 45 connects the X electrode wiring 411 and the driver IC 44. The Y electrode wiring 412 and the driver IC 44 are connected to the Y electrode routing wiring 46.

  Between the driver IC 44 and the seal portion 43, the X electrode routing wiring 45 and the Y electrode routing wiring 46 are refracted. Since the terminal pitch (eg, 40 μm) of the connection terminals of the driver IC 44 is smaller than the lead pitch (eg, 60 μm) of the X electrode lead wiring 45 and the Y electrode lead wiring 46, the X electrode lead wiring 45 and the Y electrode lead wiring 46 It is necessary to reduce the drawing pitch (width in the left-right direction on the paper) and to connect with the connection terminal. For this reason, as shown in FIG. 4, between the driver IC 44 and the seal portion 43, the X electrode routing wiring 45 and the Y electrode routing wiring 46 are refracted.

JP 09-311341

  As described with reference to FIG. 4, the portion where the routing pitch of the routing wiring is narrowed between the seal portion 43 and the connection terminal with the driver IC 44 (the routing wiring from the substrate end 411 a of the front transparent substrate 41 a in FIG. 4).

  FIG. 1 is a configuration diagram schematically showing a configuration viewed from the viewing side of a liquid crystal display device 1 according to an embodiment of the present invention. FIG. 1 shows an STN (Super Twisted Nematic) mode passive matrix liquid crystal display device as an example of the liquid crystal display device according to the present invention. In FIG. 1, 11a is a front side transparent substrate disposed on the viewing side, and 11b is a back side transparent substrate disposed opposite to the front transparent substrate and disposed on the back side (anti-viewing side). The front side transparent substrate 11a and the back side transparent substrate 11b can be formed of glass, resin, or the like.

  A display area 12 displays an image. A seal portion 13 is formed outside the display area 12 so as to surround the display area 12. The seal part 13 fixes the front side transparent substrate 11a and the back side transparent substrate 11b. A certain gap is maintained between the front transparent substrate 11a and the rear transparent substrate 11b by a spacer. Between the front side transparent substrate 11a and the back side transparent substrate 11b, liquid crystal (not shown) is sealed in a sealing space formed inside the seal portion 13. This liquid crystal is composed of STN liquid crystal. In the STN mode liquid crystal display device, the twist angle of the liquid crystal is made larger than 180 degrees, and the birefringence effect is used to increase the number of time divisions, thereby increasing the display information processing amount.

  The display area 12 includes a plurality of pixels 121 arranged in a matrix. A plurality of X electrode wirings 122 extending in the left-right direction on the paper surface are formed on the inner side (viewing side) surface of the back-side transparent substrate 11b in the display region 12. The plurality of X electrode wirings 122 are arranged at regular intervals in the vertical direction (Y direction) of the drawing. In addition, a plurality of Y electrode wirings 123 extending in the vertical direction on the paper surface are formed on the inside (anti-viewing side) surface of the front transparent substrate 11a in the display area 12. The plurality of Y electrode wirings 123 are arranged at regular intervals in the horizontal direction (X direction) of the drawing.

  Each of the X electrode wiring 122 and the Y electrode wiring 123 is formed in a straight line having a certain width, and is arranged in parallel with an adjacent electrode wiring at a certain interval. The X electrode wiring 122 and the Y electrode wiring 123 are also formed of a transparent conductor such as ITO. The X electrode wiring 122 and the Y electrode wiring 123 are arranged so as to be orthogonal to each other, and each intersection of the X electrode wiring 122 and the Y electrode wiring 123 corresponds to one pixel 121. Thus, a plurality of pixels arranged in a matrix are configured. Each pixel is not provided with an active element, and the liquid crystal display device 1 is passive matrix driving in which a driving signal is directly applied without passing through a switching element.

  The front transparent substrate 11a is smaller than the rear transparent substrate 11b, and a part of the rear transparent substrate 11b is exposed outside the substrate end 111a of the front transparent substrate 11a. A driver IC 14 is mounted outside the seal portion 13 on the exposed surface of the back side transparent substrate 11b. The liquid crystal display device 1 of this embodiment uses a COG (Chip On Glass) mounting method, and the driver IC 14 is directly on the back side transparent substrate 11b without going through an FPC (Flexible Printed Circuit). It is installed.

  The driver IC 14 outputs a display signal for image display to each of the X electrode wiring 122 and the Y electrode wiring 123. An image signal and a control signal from a control circuit (not shown) are input to the driver IC 14 via the input terminal 15 on the back side transparent substrate 11b. The driver IC 14 outputs a display signal toward the display area in accordance with a signal from the control circuit. In this example, only one driver IC 14 is mounted, and signals to all X electrode wirings 122 and Y electrode wirings 123 are output.

  The connection between the X electrode wiring 122 and the Y electrode wiring 123 and the driver IC 14 is made through a routing wiring. The plurality of X electrode wirings 122 and the driver IC 14 are connected by the plurality of X electrode routing wirings 17. The Y electrode wiring 123 and the driver IC 14 are connected to each other by a Y electrode routing wiring 18 (which includes those including the Y electrode routing wirings 18a and 18b). The X electrode routing wiring 17 and the Y electrode routing wiring 18 are formed of a transparent conductor such as ITO.

  The plurality of X electrode routing wirings 17 are formed on the back side transparent substrate 11b. The X electrode routing wiring 17 connected to the X electrode wiring 122 on the upper half of the paper surface extends in the vertical direction (Y direction) on the right end portion of the back side transparent substrate 11b, and is connected to the connection terminal portion on the right end portion of the driver IC 14. Connected. The X electrode routing wiring 17 connected to the X electrode wiring 122 in the lower half of the drawing extends in the vertical direction (Y direction) on the left side end of the back side transparent substrate 11b, and is a connection terminal portion on the left side end of the driver IC 14. Connected.

  The Y electrode routing wiring 18 includes a Y electrode routing wiring 18a formed on the front transparent substrate 11a and a Y electrode routing wiring 18b formed on the back transparent substrate 11b. The driver IC 14 is connected to the Y electrode routing wiring 18b via the connection terminal portion. The Y electrode routing wiring 18a is continuous with each of the Y electrode wirings 123, and a part thereof is formed to be bent.

  FIG. 2 is a diagram showing details of a connection portion between the driver IC 14 and the routing wirings 17 and 18. 3 is a cross-sectional view taken along the line AA ′ of FIG. A plurality of connection terminal portions arranged in a line along the side facing the display area 12 and the seal portion 13 are formed below the driver IC 14. The plurality of connection terminal portions include a plurality of Y electrode connection terminals 21 connected to the plurality of Y electrode routing wirings 18b, and a plurality of X electrode connection terminals 22 connected to the plurality of X electrode routing wirings 17, respectively. Contains.

  A connection structure between the driver IC 14 and the Y electrode routing wiring 18 will be described with reference to FIG. The driver IC 14 and the Y electrode routing wiring 18b on the back side transparent substrate 11b are connected via the Y electrode connection terminal 21 on the Y electrode routing wiring 18b. The driver IC 14 is disposed on the Y electrode connection terminal 21, and the driver IC 14 and the Y electrode connection terminal 21 are connected. For example, the connection terminal portion can be formed by a bump formed on the lower back surface of the driver IC 14 and a pad formed on the Y electrode connection terminal 21. The structure of the connection terminal portion is not particularly limited to the above configuration.

  The Y electrode routing wiring 18b extends from the outside of the seal portion 13 toward the inside of the seal portion 13 (display region 12 side). The seal portion 13 structurally connects the Y electrode routing wiring 18b and the Y electrode routing wiring 18a formed on the inner side surface of the front transparent substrate 11a. Conductive particles are mixed in the seal portion 13 and function as a transfer portion that electrically connects the Y electrode routing wire 18a and the Y electrode routing wire 18b. Note that a transfer portion can be formed separately from the seal portion 13.

  Although not shown in the drawing, the connection portion between the driver IC 14 and the X electrode routing wiring 17 via the X electrode connection terminal 22 has a structure similar to the above. The driver IC 14 and the X electrode routing wiring 17 are connected via the X electrode connection terminal 22 on the X electrode routing wiring 17. Since the X electrode routing wiring 17 is formed only on the back-side transparent substrate 11b, there is no transfer portion due to the seal portion 13.

  Returning to FIG. 2, the plurality of Y electrode routing wirings 18 b are arranged side by side in a direction along one side of the seal portion 13 (or the display region 12 or the back side transparent substrate 11 b). In the direction in which the Y electrode routing wiring 18b is arranged, each wiring pitch of the Y electrode routing wiring 18b at the seal portion outer end 131 is substantially the same as each terminal pitch of the Y electrode connecting terminal 21. For this reason, all the Y electrode routing wirings 18b extend linearly from the outside to the inside of the seal portion 13. The Y electrode routing wires 18b are formed in parallel to each other, and extend in a direction perpendicular to the side facing the seal portion 13 (or the display region 12) of the driver IC 14.

  Thus, by making the pitch at the outer end 131 of the seal portion of the Y electrode routing wiring 18b substantially the same as the pitch of the Y electrode connection terminals 21 with the driver IC 14, all the Y electrode routing wirings 18b are linearly formed. The distance from the seal portion outer end 131 to the Y electrode connection terminal 21 can be reduced, and the width of the peripheral area of the display panel can be reduced. Further, the width of the peripheral region can be further reduced by extending the Y electrode routing wiring 18b in a direction perpendicular to the side 141 facing the seal portion 13 of the driver IC 14.

  Similar to the Y electrode connection terminal 21, the X electrode connection terminal 22 is arranged side by side in a direction along one side of the seal portion 13 (or the display area 12 or the back side transparent substrate 11 b). That is, the X electrode connection terminals 22 are arranged in the same direction as the Y electrode connection terminals 21. The X electrode connection terminal 22 is formed separately on the right side and the left side of the Y electrode connection terminal 21. As described above with reference to FIG. 1, the X electrode routing wiring 17 connects the left X electrode connection terminal 22 to the X electrode wiring 122 in the lower half of the drawing, and connects the right X electrode connection terminal 22 to the drawing. It continues to the upper half X electrode wiring 122.

  In the direction in which the X electrode connection terminals 22 are arranged, each wiring pitch of the X electrode routing wiring 17 at the seal portion outer end 131 is substantially the same as each terminal pitch of the X electrode connection terminal 22. For this reason, all the X electrode routing wirings 17 extend linearly from the outside of the seal portion 13 (X electrode connection terminal 22) toward the seal portion outer end 131. All the X electrode routing wirings 17 can be formed linearly outside the seal portion, the distance from the seal portion outer end 131 to the X electrode connection terminal 22 can be reduced, and the frame area of the display panel can be reduced.

  As described above, preferably, the pitch between the terminals of all the connection terminal portions (X electrode connection terminal 22 and Y electrode connection terminal 21) arranged on one side of the driver IC and the lead wiring (X electrode) connected thereto. The wiring pitches at the outer end 131 of the seal portion of the routing wiring 17 and the Y electrode routing wiring 18b) are made substantially the same. Thereby, all the routing wirings extending from one side 141 of the driver IC 14 to the seal portion outer end 131 can be formed in a straight line, and the distance from the seal portion outer end 131 to the connection terminal portion can be more effectively reduced. Can do.

  Preferably, the connection terminal pitch and each wiring pitch of the seal portion outer end 131 are substantially the same for all the routing wires on one side of the seal portion 13 (or one side of the display area 12). As a result, all the routing wires extending from one side of the seal portion 13 are formed in a straight line, and the distance from the seal portion outer end 131 to the connection terminal portion can be more effectively reduced. Furthermore, since the routing wiring extends in the direction perpendicular to the side 141 facing the seal portion 13 of the driver IC 14, the width of the peripheral region can be further reduced.

  Here, for example, the X electrode connection terminal 22 may be formed on the left and right sides 142 and 143 of the driver IC 14. Even in this case, the width of the peripheral region is reduced by extending all the lead wires in a direction perpendicular to the virtual straight line between the virtual straight line that overlaps the side 141 of the driver IC 14 and the outer end 131 of the seal portion. can do. This also applies to the case where the X electrode connection terminals 22 are arranged along the seal portion outer end 131 as shown in FIG.

  Although the driver IC 14 is formed on the rear transparent substrate 11b, the driver IC 14 may be mounted on either the front transparent substrate 11a or the rear transparent substrate 11b. In the above example, one driver IC outputs signals to different types of electrode wirings, but it is also possible to connect a plurality of driver ICs. In this example, a passive matrix liquid crystal display device is described. However, the present invention can be applied to an active matrix liquid crystal display device. The present invention is not limited to a liquid crystal display device, and can be applied to other types of display devices such as an organic EL (Electro Luminescence) display device.
