3 dated eventsAbstract
Techniques are provided for unifying steps of sealing material so that the yield and the reliability of a liquid-crystal display device become high. A starting film of scanning lines is patterned so that prismatic dummy wirings 301 for the first layer which are not electrically connected are formed in regions R 1 and R 2 , and wirings 302 extending from the pixel section are formed in a region R 3 , and wirings 303 having connection end portions 303 a are formed in a region R 4 . After an interlayer insulation film is formed, the starting film of the signal lines is patterned so that the dummy wirings 304 for the second layer are formed to embed the gaps between the wirings 301 to 303 , and also the wirings 305 and the wirings 303 which extend from the pixel portion are connected to each other. This permits unification of the cross-sectional structure of the sealing material formation region.
