Patent ID: 7760315

Claim:
An electro-optical device, comprising: a substrate having terminals and wiring lines arranged thereon, the wiring lines being connected to the terminals and extending in a first direction, the terminals being divided into at least one first terminal group and at least one second terminal group that does not overlap the first terminal group in the first direction, each of the first and second terminal groups having at least three terminals that do not overlap each other in plane view, each terminal of the first and second terminal groups having a width in a second direction that intersects the first direction, in each pair of adjacent terminals in each of the first and second terminal groups, one of the adjacent terminals having a first portion and a second portion, the first portion overlapping the width of the other terminal in the first direction, the second portion being located without overlapping the width of the other terminal in the first direction, one of the wiring lines being connected to the second portion; and an electronic component mounted on the substrate with an adhesive; wherein the wiring lines connected to the second portions of the terminals of the first terminal group extend between a first terminal of the first terminal group and a first terminal of the second terminal group; the wiring lines connected to the second portions of the terminals of the first terminal group extend linearly in the first direction at least between the first terminal of the first terminal group and the first terminal of the second terminal group; and the electro-optical device further comprises: second wiring lines extending in the first direction and electrically connected to the first portions of the terminals of the first and second terminal groups at sides opposite to where the wiring lines are electrically connected to the respective second portions.
