Abstract
A dummy electrode 217 having an L-shape as a whole in plan view is formed on a surface of an element substrate 210 so that a dummy electrode unit 217a which is disposed on the side opposite to the side on which a scanning line 221 of a liquid crystal drive area S is formed outside the liquid crystal drive area S extending along and substantially parallel to a data line 211 is continuous to a dummy electrode 217c passing between a connection unit 211a of the data line 211 and an input terminal 213. The dummy electrode 217 is not formed on the scanning line 221 side of the liquid crystal drive area S.
Claims9
An electro-optical device comprising:
- an electro-optical substance disposed between a first substrate and a second substrate;
- said first substrate including a plurality of first wires extending in a predetermined direction, pixel electrodes connected to said first wires via an active element, terminal, and a semiconductor circuit connected to said first wires and said terminal;
- said second substrate including opposing electrodes disposed so as to oppose said pixel electrodes and a plurality of second wires connected to said opposing electrodes and provided on one side of said second substrate in a direction substantially orthogonal to said predetermined direction;
- drive area where said pixel electrodes face said opposing electrodes via said electro-optical substance;
- and
- said first substrate further comprising a first dummy electrode, said first dummy electrode having a first dummy electrode unit extending along said first wires and being placed outside said drive area on the side opposite to said one side where said second wires are provided and a second dummy electrode unit passing between said first wires and said terminal, said first unit being formed continuously with said second unit and said one side being free of said first dummy electrode.
An electro-optical device comprising:
- a first substrate having a substrate expansion portion;
- a plurality of first wires formed on said first substrate;
- pixel electrodes connected to said first wires;
- a second substrate disposed opposite said first substrate;
- a plurality of second wires formed on said second substrate;
- opposing electrodes disposed opposite said pixel electrodes and connected to said second wires;
- an electro-optical substance disposed between said first and second substrate;
- a drive area where said pixel electrodes that face said opposing electrodes via said electro-optical substance is formed;
- and
- a first dummy electrode having a first dummy electrode unit extending along said first wires and being placed outside of said drive area on a side opposite said second wires and a second dummy electrode unit passing between said first wires and terminal, said second dummy electrode unit being formed continuously with said first dummy electrode unit and terminating at a free end on said substrate expansion portion.
