Abstract
Provided is a thin three-dimensional interactive display which enables multi-touch sensing and three-dimensional gesture recognition. The three-dimensional interactive display includes a light source for irradiating an object to be detected with a light, a light modulation layer, into which a scattered light generated by irradiating the object with the light from the light source enters, at least for modulating an intensity of the scattered light, a transparent light-receiving layer for receiving the light transmitted through the light modulation layer, and a display panel or a back light panel disposed on the opposite side of the transparent light-receiving layer from the light modulation layer. The transparent light-receiving layer has a two-dimensional array of light-receiving elements.
