Abstract
To provide a sensor panel and a sensor sheet, in which a conductive fine line and a silhouette of the conductive fine line is difficult to be seen through a display portion during illumination and in which the visibility of the display portion during illumination is good. A light diffusion layer is provided on the sensor sheet, the light diffusion layer diffusing a light of an internal light source L and transmitting the light to sensor electrodes.
Claims7
A sensor panel, comprising:
- a panel substrate;
- a decorative layer provided on a first surface side of the panel substrate;
- and
- a sensor sheet provided on a second surface side of the panel substrate opposite from the first surface side;
- a display portion that is illuminated by an internal light source;
- and
- an input operation performed from a front surface side of the panel substrate,
- wherein the sensor sheet has
- a sensor electrode layer including a conductive fine line provided on the back surface side of the panel substrate,
- a diffusion layer provided between the sensor electrode layer and the internal light source, the diffusion layer diffusing a light of the internal light source and transmitting the light to the sensor electrode layer, and
- an interlayer distance T that is a distance in which the decorative layer and the sensor electrode layer of the sensor sheet are set apart, and a line width W of a conductive fine line satisfies
- T≥20W.
