Patent ID: 8035790

Claim:
An electro-optic device, comprising: an electro-optic panel; and a connecting board mounted to the electro-optic panel; wherein the electro-optic panel has a first terminal group including a plurality of first terminals; the connecting board has a second terminal group including a plurality of second terminals conductively connected to the corresponding first terminals of the first terminal group; the range in which the electro-optic panel and the connecting board are mounted includes a terminal region in which the first terminals are arrayed substantially with an equal pitch, and a no-terminal region in which there are no first terminals; and the second terminal group has in the terminal region, the second terminals arrayed in correspondence with the first terminals, respectively, and at least a dummy terminal provided in the no-terminal region only in a position immediately adjacent to the second terminal at an edge of the terminal region, wherein the first terminals are linear and a plurality of the first terminals converge toward a first common point, and wherein the second terminals are linear and a plurality of the second terminals converge toward a second common point.
