A liquid crystal device comprises a pair of substrates 2a and 2b, liquid crystal L held between the substrates 2a and 2b, and an IC 13 mounted on an overhang section 2c of the substrate 2a. A terminal column 26a comprises a plurality of terminals 18 aligned in a direction away from the liquid crystal L. The terminal column 26a has, 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 AB.
