Patent ID: 7167227

Claim:
An electrooptic device comprising an electrooptic material, a substrate for supporting the electrooptic material, and an IC chip mounted on the substrate, the IC chip comprising: a first terminal column comprising a plurality of terminals arranged in a direction away from the electrooptic material; and a second terminal column disposed along a first side of the IC chip close to the electrooptic material, the second terminal column comprising a plurality of terminals arranged in parallel to the electrooptical material; the first terminal column comprising a first noneffective terminal region having at least two consecutive noneffective terminals within a distance “A” from the first side of the IC chip, and an effective terminal region continuing from the first noneffective terminal region, the second terminal column comprising a second noneffective terminal region having at least two consecutive noneffective terminals within a distance “C” from a second side of the IC chip and an effective terminal region continuing from the third second noneffective terminal region, wherein A>C; and the second noneffective terminal region adjoins the first noneffective terminal region and extends in a direction substantially perpendicular to a direction in which the first noneffective terminal region extends.
