摘要

Detection column wires and detection row wires are configured of thin wires made of a conductive material having light reflectivity, such as a metal or alloy including silver and aluminum. A predetermined plural number of detection column wires are electrically connected to form a plurality of column-direction bundle wires. A predetermined plural number of detection row wires are electrically connected to form a plurality of row-direction bundle wires. A reflected-light distribution pattern is further provided. When viewed in a direction vertical to the surface of the touch screen, the reflected-light distribution pattern includes a curved portion, and the normal lines of the curved portion head for all directions.

主权项

1. A touch screen comprising:
a plurality of column wires extending in a predetermined column direction, the column wires being arranged at intervals in a row direction crossing said column direction; a plurality of row wires extending in said row direction, the row wires being arranged at intervals in said column direction; and a transparent base made of a translucent material, the transparent base being provided with said column wires and said row wires which are electrically separated from each other and crossing each other in a three-dimensional way, wherein said column wires and said row wires are made of a conductive material having light reflectivity, a predetermined plural number of said column wires are electrically connected to form a plurality of column-direction bundle wires, a predetermined plural number of said row wires are electrically connected to form a plurality of row-direction bundle wires, said transparent base is provided with a reflected-light distribution pattern made of a light reflective material, said reflected-light distribution pattern includes a curved portion shaped in a curved manner when viewed in a direction vertical to a surface of said transparent base facing a user, and is disposed such that normal lines of said curved portion head for all directions, and said curved portion of said reflected-light distribution pattern includes at least one of said row-direction bundle wires and said column-direction bundle wires such that said curved portion of said reflected-light distribution pattern and said at least one of said row-direction bundle wires and said column-direction bundle wires are formed in a single layer.
