[SUMMARY OF THE INVENTION Incidentally, the known liquid crystal display device, in order to uniform the respective wiring electrodes 42 _1, 42 ₂ of the resistance value, the first wiring portion 36 ₁ and the second wiring portion 3
Since the first wiring electrode 42 ₁ and the second wiring electrode 42 ₂ of the width forming each 6 ₂ are formed by changing in inverse proportion to their lengths, the first wiring portion 36 ₁ and the second
Wiring electrodes share in the wiring portion 36 _2, i.e., the area ratio of the first wiring electrode 42 ₁ and the second wiring electrode 42 ₂ of the forming portion and the non-formation portion becomes different depending on the location, in the same manner, first Dummy wiring part 37 ₁ and second dummy wiring part 3
The first dummy wiring electrode 43 are formed respectively on 7 ₂
Since ₁ and second dummy wiring electrode 43 ₂ of width are formed while changing in inverse proportion to their lengths, the dummy wiring electrode occupancy in the first dummy wiring part 37 ₁ and the second dummy wiring section 37 ₂ Will also vary by location.

And a dummy wiring portion on which a large number of dummy wiring electrodes are formed are arranged at opposing positions, and a large number of dummy wiring electrodes are formed at locations opposed to the formation locations of the large number of wiring electrodes, respectively.
A frame-shaped sealing material is brought into contact with each part of a large number of wiring electrodes and a large number of dummy wiring electrodes, and the width of the large number of wiring electrodes is formed so as to be inversely proportional to the length thereof. The width of the portion of the electrode that abuts on the frame-shaped sealing material was formed to be partially equal, and the area where many wiring electrodes and many dummy wiring electrodes overlapped on the portion that was in contact with the frame-shaped sealing material were equalized. Means.

According to the above means, in the portion where the frame-shaped sealing material abuts on the large number of dummy wiring electrodes, the width of the large number of dummy wiring electrodes is formed to be partially equal, so that the large number of wiring electrodes and the large number of dummy wiring electrodes are formed. Since the areas where the wiring electrodes overlap each other are equal, the number of effective space members in the frame-shaped sealing material becomes substantially uniform as a whole.
Since the arrangement intervals of the transparent insulating substrates are entirely constant, there is no display unevenness during liquid crystal display.
