Abstract:
An optical touch film includes a sensor layer, an optical film, an adhesive layer, a separation layer, and a refractive insulating layer. The sensor layer includes touch electrodes forming a sensor. The adhesive layer is between the sensor layer and the optical film. The separation layer is on a surface of the sensor layer. The separation layer includes an organic polymer material. The refractive insulating layer is on the touch electrodes. A refractive index of the refractive insulating layer is greater than a refractive index of the separation layer.
