Touch screen with electrodes including linear and branched portions
First Claim
1. A touch screen comprising:
- a substrate which includes a main surface;
a first electrode which is disposed on said main surface and includes a plurality of first wires, said plurality of first wires being detection wires, and each of the first wires including a first linear portion and a plurality of first branch portions, said first linear portion extending in a first direction, said plurality of first branch portions being branched from said first linear portion;
an insulation film which is disposed on said main surface; and
a second electrode which is disposed on said main surface, is insulated from said first electrode by said insulation film, and includes a plurality of second wires, said plurality of second wires being excitation wires, and each of the second wires including a second linear portion and a plurality of second branch portions, said second linear portion extending in a second direction which is not parallel to said first direction, said plurality of second branch portions being branched from said second linear portion, said second linear portion three-dimensionally intersecting said first linear portion and not three-dimensionally intersecting said plurality of first branch portions, said plurality of second branch portions each including a rim portion, said second linear portion and said rim portion surrounding a cavity portion formed at each of said plurality of second branch portions, said rim portion including a portion parallel along an outline of said first linear portion or said plurality of first branch portions and not including a portion parallel along an outline of said second linear portion when seen in a plan view in a normal direction of said main surface.

Abstract
In a touch screen, a lower electrode is insulated from an upper electrode by an insulation film. A column direction wire of the upper electrode includes a first linear portion which extends in a row direction, and first branch portions which are branched from the first linear portion. A row direction wire of the lower electrode includes a second linear portion which extends in a column direction, and second branch portions which are branched from the second linear portion. The second linear portion three-dimensionally intersects the first linear portion, yet does not three-dimensionally intersect first branch portions. A rim portion of each of second branch portions includes a portion parallel along an outline of the first linear portion or first branch portions, yet does not include a portion parallel along an outline of the second linear portion. At each of second branch portions, a cavity portion is formed.
