Patent ID: 7177136

Claim:
A wiring board comprising: a substrate; a bank which is disposed above the substrate to provide a plurality of regions; and a conductive layer and first and second interconnecting lines formed between the substrate and the bank, the bank having a top surface and a pair of side surfaces provided on both sides of the top surface, the side surfaces sloping symmetrically with respect to the substrate, the first interconnecting line being formed in a position closer to the substrate than the second interconnecting line, and the vertical centerline of the first interconnecting line not coinciding with the vertical centerline of the second interconnecting line; the conductive layer being formed in a position closer to the substrate than the second interconnecting line, and the vertical centerline of the conductive layer not coinciding with the vertical centerline of the second interconnecting line; and the conductive layer and the first interconnecting line respectively having portions which are not located under the second interconnecting line, and the portions extending in opposite width directions.
