As shown in FIG. 1, the liquid crystal display device A has a structure in which a rectangular first substrate 2 having a large area and a rectangular second transparent substrate 3 having a small area are bonded to each other, as shown in FIG. As described above, the inner surface of the first substrate 2 is made of ITO (Indium Tin Oxide) or the like, and a plurality of one electrodes extending in one direction are formed in stripes. The plurality of electrodes is one electrode group 4. On the inner surface of the second substrate 3, as shown in FIG. 4, a plurality of other electrodes made of the ITO or the like and extending in the other direction, which is a direction orthogonal to one direction, are formed in stripes. The plurality of electrodes is the other electrode group 5. The two electrode groups 4 and 5 are orthogonal to each other to form the display region 6. Each of these electrode groups 4 and 5 is covered with an alignment film (not shown) made of polyimide synthetic resin or the like. Then, a spacer is arranged between the first substrate 2 and the second substrate 3 so as to maintain a predetermined distance, and both the substrates 2 and 3 are bonded together with the seal member 7, and thereafter, the STN is interposed between these two substrates. Or the like filled with liquid crystal L.
  The display area is divided into two blocks by dividing the other electrode group 5 of the second substrate 3 into two blocks. In FIG. 1, the block is divided into an upper block and a lower block with a block boundary line 17 as a boundary. The one electrode group 4 formed on the first substrate extends in common to the two blocks.
  On the first substrate 2, drive element connection terminals 8 are formed in the vicinity of one edge (these are indicated by dotted elliptical areas in FIG. 1). The connection configuration is described below.
  First, the one electrode group 4 formed on the first substrate 2 is connected by extending the one electrode connection wiring 9 from the drive element connection terminal 8 to the one electrode 4. That is, the one electrode group 4 formed on the first substrate 2 is formed with one electrode connection wiring 9 having one end extending through one side of the seal member 7.
  For the connection of the other electrode group 5, the other electrode connection wirings 10 and 11 extend from the drive element connection terminal 8 on the first substrate 2. For example, the other electrode connection wiring 10 is connected to one side of the pair of other sides of the seal member 7. The first conductive connection portion 12 extends. The other electrode connection wiring 11 extends to the second conductive connection portion 13 on the other side of the pair of other sides of the seal member 7. The conductive connection portions 12 and 13 are connected to the other electrode connection wirings 10 and 11 of the second substrate 3.
  That is, the other electrode connection wiring 10 provided on the first substrate 2 between the drive element connection terminal 8 and the first conductive connection portion 12 is provided between the drive element connection terminal 8 and the second conductive connection portion 13. The other electrode connection wiring 11 provided on the first substrate 2 is formed by being distributed to the left and right in the drawing, and the other electrode extension wiring 15 extending to each side of the other electrode group 5 formed on the second substrate 3. The other electrode extended wiring 16 is electrically connected through the seal member 7. As shown in FIG. 2, the sealing member 7 is mixed with conductive particles 14 (such as particles plated with Au on the surface of the plastic particles), for example, the other electrode connection wiring 10 of the first substrate 2 and the second substrate 3. The other electrode extension wiring 15 is electrically connected. This conductive connection portion exists on the other side portion (left side portion) of the seal member 7 and becomes the first conductive connection portion 12. Similarly, the conductive connection portion of the other electrode connection wiring 11 of the first substrate 2 and the other electrode extension wiring 16 of the second substrate 3 exists in the other side portion (right side portion) of the seal member 7 and is the second conductive. It becomes the connection part 13.
  And the 1st conductive connection part 12 and the 2nd conductive connection part 13 are arranged near the other side part center part (center part of the up-down direction of drawing) of the sealing member 7. FIG. Each of the first conductive connection portion 12 and the second conductive connection portion 13 is disposed beyond the block boundary line 17 that is the center of the other side of the seal member 7 as shown in FIG.
Further, at least one of the other electrode connection wiring 10 and the other electrode connection wiring 11 on the first substrate 2 is formed obliquely at a portion where the display region 6 and the seal member 7 are in parallel as shown in FIG. The width of the portion b drawn obliquely from the portion a parallel to the seal member 7 is made thicker.
  FIG. 6 and FIG. 7 show liquid crystal devices B and C provided with a drive element for the liquid crystal display device A having the above-described configuration.
In the liquid crystal display device B2 shown in FIG. 6, a drive element (IC) 18 having both segment side and common side output functions is directly mounted on the first substrate 2 by a COG (Chip On Glass) method. ing. Then, the external wiring substrate 19 is connected to the driving element 18 and a control signal is supplied from the outside to drive the driving element 18 to display a liquid crystal.
The liquid crystal display device C shown in FIG. 7 is formed by using a film or the like, that is, a TCP (Tape Career Package) or a COF (Chip On Film) at the end of the liquid crystal display device. These are arranged, and these are crimped to the connection terminal 8 of the first substrate 2 via an anisotropic conductive material.
  According to the liquid crystal display devices B and C having the above-described configuration, the conductive portions (the first conductive connection portion 12 and the second conductive connection portion 13) are arranged close to the central portion of the other side portion of the seal member 7. Compared to the conventional case, the difference between the maximum value and the minimum value of the wiring resistance is reduced.
  The inventor manufactured a color type liquid crystal display device A having a dot format of 128 × 160. The position of the conductive portions 12 and 13 is set to the center of the other side of the seal member 7, and the first conductive connection portion 12 in FIG. When the wiring resistance value from the drive element connection terminal 8 to the other electrode group 5 was measured by placing ΔC1 of about 1.5 mm and ΔC2 of the second conductive connection portion 13 about 2 mm closer to each other, the liquid crystal of the present invention was measured. The result of the present invention shown in FIG. The horizontal axis of FIG. 13 is the number of the output terminal of the drive element 18 for the display area 6 of the liquid crystal display device A (output No. indicates the output display order of the other electrode group 5), and the vertical axis is applied to the other electrode group 5. Wiring resistance value (Ω).
  As a comparative example, in the conventional liquid crystal display device X, the conductive portion was placed on the extension line with respect to the other electrode 5 and the wiring resistance value was measured. As a result, the result of the prior art as shown in FIG. 13 was obtained. .
  As is clear from these results, the liquid crystal display device A of the present invention has a higher minimum resistance value (output No. 1) and a lower maximum resistance value (output No. 160) than the conventional liquid crystal display device X. This shows that the difference between the maximum resistance value (output No. 160) and the minimum resistance value (output No. 1) is small.
  In other words, the conductive portions (the first conductive connection portion 12 and the second conductive connection portion 13) are arranged close to the center of the other side of the seal member 7, and the other electrode connection wiring 10 is arranged as shown in FIG. 11 between the display region 6 and the seal member 7 and between the first conductive connection portion 12 and the second conductive connection portion 13 and the drive element connection terminal 8 are obliquely routed with respect to the arrangement direction of the seal member 7. By adjusting the wiring width and wiring length, the wiring resistance value connected to the other electrode group 5 and the resistance difference between the maximum resistance value and the minimum resistance value can be reduced.
  Further, the other electrode group 5 is divided into two blocks, and the other electrode adjacent to the block division boundary line 17 has the same wiring resistance as the other electrode connection wirings 10 and 11 connected thereto, so that the blocks in the display area 6 are blocked. As shown in FIG. 13, the wiring resistance difference at the boundary disappeared and the wiring resistance was smooth, and display quality without display unevenness was obtained.
  Thus, in the liquid crystal display devices A, B, and C of the present invention, high display quality without display unevenness was obtained.
  In particular, in color liquid crystal display, since color colors are sharply displayed, display unevenness becomes noticeable as color unevenness, but the present invention is most effective in that respect.
  In addition, this invention is not limited to the said embodiment, A various change, improvement, etc. do not interfere in the range which does not deviate from the summary of this invention.
For example, although the other electrode connection wirings 10 and 11 are formed of a transparent conductive film such as ITO, the wiring resistance may be lowered by forming a part or the whole with a metal film such as aluminum instead.
