ABSTRACT:
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 wirings301for the first layer which are not electrically connected are formed in regions R1and R2, and wirings302extending from the pixel section are formed in a region R3, and wirings303having connection end portions303aare formed in a region R4. After an interlayer insulation film is formed, the starting film of the signal lines is patterned so that the dummy wirings304for the second layer are formed to embed the gaps between the wirings301to303, and also the wirings305and the wirings303which extend from the pixel portion are connected to each other. This permits unification of the cross-sectional structure of the sealing material formation region.
