A liquid crystal device comprises a pair of substratesand, liquid crystal L held between the substratesand, and an ICmounted on an overhang sectionof the substrate. A terminal columncomprises a plurality of terminalsaligned in a direction away from the liquid crystal L. The terminal columnhas, in the order of the closeness to the liquid crystal L, a first noneffective terminal region within a distance 'A' from a first side of the IC, an effective terminal region X continuing from the first noneffective terminal region, and a second noneffective terminal region within a distance 'B' from a second side of the IC, the second noneffective terminal region continuing from the effective terminal region. The distances A and B are adjusted to satisfy the relationship A&#x3e;B.
