An image display device for superimposing a plurality of images generated from a plurality of graphics data and for displaying the superimposed images on a display screen, comprising: an input means (1, 2, 4) for inputting said graphics data (201 - 204), layout information (101 - 104) that defines a display layout of the images generated from said graphics data (201 - 204) on the display screen for each of layers to which said images belong, and layer structure information that describes a layered structure (10, 13, 16) of the layers to which the images generated from said graphics data (201 - 204) belong and that includes operation status (11, 14, 17), wherein the operation status defines whether to make an image for each of the layers visible or non-visible, and defines whether to make a moving image for each of the layers reproduction or stop; a control means for setting up information on display positions, drawing order and the operation status on said display screen of the images generated from said graphics data (201 - 204) input by the input means (1, 2, 4) for each of the layers on a basis of said layout information (101 - 104) and said layer structure information; a data transferring means for transferring the graphics data (201 - 204) input by the input means (1, 2, 4) to a display memory on a basis of the information set up by the control means; a layer structure changing means for changing the layered structure of the layers of the layer structure information; and a status changing means for changing the operation status on the display screen of an image generated from said graphics data on a layer-by-layer basis, wherein the image display device is configured such that, if the status changing means changes such operation status of a layer from visible to non-visible and from reproduction to stop, an image in this layer can be made non-visible and stop, wherein the layer structure changing means and the status changing means are adapted to change the display positions of the images generated from said graphics data (201 - 204) by changing the description of the layer structure information and the description of said layout information (101 - 104). an input means (1, 2, 4) for inputting said graphics data (201 - 204), layout information (101 - 104) that defines a display layout of the images generated from said graphics data (201 - 204) on the display screen for each of layers to which said images belong, and layer structure information that describes a layered structure (10, 13, 16) of the layers to which the images generated from said graphics data (201 - 204) belong and that includes operation status (11, 14, 17), wherein the operation status defines whether to make an image for each of the layers visible or non-visible, and defines whether to make a moving image for each of the layers reproduction or stop; a control means for setting up information on display positions, drawing order and the operation status on said display screen of the images generated from said graphics data (201 - 204) input by the input means (1, 2, 4) for each of the layers on a basis of said layout information (101 - 104) and said layer structure information; a data transferring means for transferring the graphics data (201 - 204) input by the input means (1, 2, 4) to a display memory on a basis of the information set up by the control means; a layer structure changing means for changing the layered structure of the layers of the layer structure information; and a status changing means for changing the operation status on the display screen of an image generated from said graphics data on a layer-by-layer basis, wherein the image display device is configured such that, if the status changing means changes such operation status of a layer from visible to non-visible and from reproduction to stop, an image in this layer can be made non-visible and stop, wherein the layer structure changing means and the status changing means are adapted to change the display positions of the images generated from said graphics data (201 - 204) by changing the description of the layer structure information and the description of said layout information (101 - 104).
