Abstract
An improved touch sensor comprising a difference in optical characteristics between an electrode region where the transparent electrode is formed and an inter-electrode region where the transparent electrode is not formed, resulting in the prevention of a transparent electrode from being visible to a user. The improved touch sensor further results in the prevention of a reduction in light transmittance caused by the transparent electrode and the prevention a reduction in optical quality due to a moiré phenomenon.
