Abstract
An improved touch sensor comprising a first sensing electrode unit formed on a substrate in a first direction and a second sensing electrode unit formed on the substrate in a second direction crossing the first direction. A plurality of fine etching patterns are formed in boundary portions of unit transparent electrodes included in the first sensing electrode unit and the second sensing electrode unit. Each unit transparent electrode may have a shape in which a portion of a curved line connecting the vertices of a polygon is removed. Adjacent unit transparent electrodes may be electrically connected to one another. The improved touch sensor prevents a transparent electrode from being visible to a user sensor and also results in the prevention of a reduction in light transmittance caused by the transparent electrode as well as the prevention a reduction in optical quality due to a moiré phenomenon.
