Patent ID: 7663306

Claim:
An electrooptic device comprising: a first substrate; and a second substrate, the first substrate including: an electrooptic element in which an electrooptic substance is interposed between a first electrode and a second electrode, the electrooptic element being disposed on a surface of the first substrate that opposes the second substrate; an electronic element for driving the electrooptic element; and a power supply wire connected to the electronic element, and the second substrate including: a auxiliary wire connected to of the electrooptic element, the auxiliary wire being disposed on a surface of the second substrate that opposes the first substrate, the auxiliary wire having a planar shape that corresponds with a non-opening region of the electrooptic element, wherein the second electrode is closer to the second substrate than the first electrode is; a spacer for regulating the distance between the first substrate and the second substrate is disposed on the first substrate or the second substrate such that the spacer is adjacent to the electrooptic element; and a connecting portion for supplying power from the auxiliary wire to the second electrode is disposed on a surface of the spacer, wherein a connecting part at which the first substrate is electrically connected to the auxiliary wire has a metal junction or metal bridge formed therein; wherein, in the connecting portion, the area of the auxiliary wire opposing the second electrode is larger than the area of the second electrode opposing the auxiliary wire.
