Abstract

See full text

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.
