Claim:
1. A stereoscopic image displaying device comprising: an outer surface that a detection target object approaches; a stereoscopic image display panel that generates a three-dimensional stereoscopic image based on an input video signal; a display control unit that controls the stereoscopic image display panel such that an image displaying height at which the stereoscopic image is generated can be changed according to parallax information included in the input video signal; a proximity sensor unit which has at least a portion that is disposed at a side of the outer surface and which detects, with a detection range in a direction of the image displaying height, proximity of the detection target object with respect to the outer surface, the detection range having an upper limit that is substantially the same as the image displaying height; the proximity sensor unit including; a plurality of detection electrodes that are separated in a second direction different from the first direction and that are disposed to face the driving electrodes, the detection electrodes being capacitively coupled with the driving electrodes and having electric potentials changing in accordance with proximity of the detection target object; and a detection determining unit that determines detection of the detection target object based on an output signal output from the proximity sensor unit and which has a variable detection range; wherein in a two dimensional display mode in which the two-dimensional display image is output from the outer surface, the driving electrodes are driven in an united manner; wherein, in a three dimensional display mode in which the stereoscopic image is output from the outer surface, the driving electrodes of an electrode group are driven in a tied manner in a unit period, the electrodes group includes k (k is an integer of two or more) driving electrodes, which are adjacent in the first direction in the unit period, and which in the subsequent unit period, are shifted in the first direction by s (s is an integer that is equal to or greater than one and smaller then k) driving electrodes; wherein the stereoscopic image display panel generates an image different from the stereoscopic image that is displayed when the detection determining unit determines detections of the detection target object, upon a timing before the detection target object comes into contact with the outer surface; and wherein the stereoscopic image display panel generates a plurality of selectable three-dimensional stereoscopic images and a predetermined detection range is different for at least two of the stereoscopic images based on different parallax information for the selectable three-dimensional stereoscopic images.
