[Constitution] When a user holds a cell phone such that a first switching key 8 comes closer to the user's body, this makes the user push the first switching key 8. If the user pushes the first switching key 8, a CPU 100 displays a display image such that a display direction becomes a first direction where the first switching key 8 comes downside. If the user holds the cell phone such that a second switching key 9 comes closer to the user's body, this makes the user push the second switching key 9. If the user pushes the second switching key 9, the CPU 100 displays the display image such that the display direction becomes a second direction where the second switching key 9 comes downside. ## Claims ### Claim 1 An image display device comprising a display area having a display region on which an image is displayed, a display controller which controls a display of the image, an operating portion for setting display directions of the image, the operating portion comprising first and second operating portions disposed on both sides of a central portion of the display region, and a position detector which detects a position on the display region designated by a user, wherein the display controller lines up an image for providing information and an image for carrying out operation/inputting operation on the display region in one of the display directions corresponding to an operation to the operating portion such that a positional relation of the images is maintained in the respective display directions, and a display direction of the image for providing the information and the image for carrying out the operation/inputting operation is determined based on which of the first and second operating portions is operated, and the position detector is disposed such that a detection region of the position detector covers a region where the image for carrying out the operation/inputting operation is located in the respective display directions which can be set through the operating portion. ### Claim 2 (depends on 1) The image display device according to claim 1, wherein when the first operating portion is operated, the display controller displays the image for providing the information and the image for carrying out the operation/inputting operation in a direction where the first operating portion comes downside, and when the second operating portion is operated, the display controller displays the image for providing the information and the image for carrying out the operation/inputting operation in a direction where the second operating portion comes downside. ### Claim 3 (depends on 1) The image display device according to claim 1, wherein the first and second operating portions are disposed on the display region. ### Claim 4 (depends on 3) The image display device according to claim 3, wherein the first and second operating portions are disposed at locations of opposing corners on the display region. ### Claim 5 (depends on 1) The image display device according to claim 1, further comprising a viewing direction determining section which determines the user's viewing direction of the image for providing the information and the image for carrying out the operation/inputting operation, wherein when an operation for setting the display direction to a direction different from the viewing direction is carried out through the operating portion, the display controller cancels this operation. ### Claim 6 (depends on 5) The image display device according to claim 5, wherein the viewing direction determining section includes an inclination detector which detects an inclination of the image display device from a horizontal plane, the viewing direction determining section compares the inclination detected by the inclination detector with a threshold value, and determines the viewing direction. ### Claim 7 An image display device comprising a display area having a display region on which an image is displayed, a display controller which controls a display of the image, and an operating portion for setting display directions of the image, the operating portion comprising first and second operating portions disposed on both sides of a central portion of the display region, wherein the display controller lines up an image for providing information and an image for carrying out operation/inputting operation on the display region in one of the display directions corresponding to operation to the operating portion such that a positional relation of the images is maintained in the respective display direction, and a display direction of the image for providing the information and the image for carrying out the operation/inputting operation is determined based on which of the first and second operating portions is operated.
