Abstract:
1. A portable electronic device comprising: a device body; a first image display panel provided on a front surface of the device body; a second image display panel disposed on the front surface of the device body and overlapping with an image display surface of the first image display panel; a coupling portion for slidably coupling the second image display panel to the device body to reciprocate the second image display panel along a predetermined path over the image display surface of the first image display panel, wherein a length of the portable electronic device is not varied by movement of the second image display panel along said predetermined path; a third image display panel disposed on the front surface of the device body and overlapping with the image display surface of the first image display panel; and a fixing portion for fixing the third image display panel such that the third image display panel is not able to move relative to the device body and is fixed over an end portion of the image display surface of the first image display panel; wherein both the second image display panel and the third image display panel have a structure in which light incident from a back surface side of the respective image display panel is transmitted toward a side of an image display surface of the respective image display panel, and wherein the image display surface of at least one of the first image display panel: the second image display panel, and the third image display panel is provided with an inputting touch panel having a light transmittance while covering at least a partial region of the image display surface thereof; and wherein an image display surface of the third image display panel is provided with an inputting touch panel having a light transmittance while covering at least a partial region of the image display surface of the third image display panel, and wherein the device body includes a state detecting portion for detecting an opening state in which the second image display panel and the third image display panel are opened apart from each other and/or a closing state in which the second image display panel and the third image display panel are close to each other or in contact with each other; and a changing portion for changing directions of images to be displayed on the first image display panel, the second image display panel, and the third image display panel depending on the state detected by the state detecting portion.
