Abstract
An electrode driving apparatus includes first through third electrode patterns 21–23 arranged in a quadrilateral region 20, first through third wiring patterns 31–33, and first through third terminals 41–43. With the third wiring pattern 33 being defined as a boundary, the first terminal 41 is disposed on the side of the first wiring pattern 31, and the second terminal 42 is disposed on the side of the second wiring pattern 32. The third terminal 43 is disposed between the first terminal 41 and the second terminal 32.
Claims23
An electrode driving apparatus comprising:
- first and second electrode patterns arranged in a quadrilateral region;
- a first substrate having the first and second electrode patterns formed therein;
- a first wiring pattern electrically connected to the first electrode pattern and formed outwardly from a first side of the quadrilateral region;
- a second wiring pattern electrically connected to the second electrode pattern and formed outwardly from a second side adjacent to the first side of the quadrilateral region;
- a third wiring pattern independent of the first and second electrode patterns extending outward from a corner of the quadrilateral region between the first side and the second side and positioned between the first wiring pattern and the second wiring pattern;
- a second substrate disposed opposite to the first substrate;
- a third electrode pattern formed in the second substrate and electrically connected to the third wiring pattern;
- a first electronic component including a first terminal electrically connected to the first wiring pattern;
- and
- a second electronic component including a second terminal electrically connected to the second wiring pattern and a third terminal electrically connected to the third wiring pattern, a first distance between the first and the second terminals is greater than a second distance between the third terminal and at least one of the first terminal and the second terminal;
- wherein the first electronic component is between the quadrilateral region and the second electronic component such that the first electronic component is closer to the quadrilateral region than the second electronic component.
