摘要：
A capacitance-type touch sensor and a display device equipped with this sensor are provided in which the detection of the transparent conductive portions can be suppressed without employing a technique using a dummy electrode. The capacitance-type touch sensor of the present invention includes a resin sheet and a plurality of transparent conductive portions formed in parallel on the resin sheet. In this capacitance-type touch sensor, the difference between the maximum and minimum retardation values of a resin sheet equipped with transparent conductive portions is 3 nm or less.
