Provided are an image display device in which a desired number of panels are combined so that a large light-emitting surface is realized, a panel provided in the image display device, and a method for manufacturing the panel. For this purpose, a panel (11) of the present invention includes a rectangular light-emitting section (13); a substrate (12) having a flat surface (12a′) on which the rectangular light-emitting section (13) is provided and a curved adjacent surface (12b′) that is adjacent to one of edge portions of the flat surface which extend along long sides of the rectangular light-emitting section (13); and a terminal group that is drawn out from a long side of the rectangular light-emitting section (13) and that is disposed in the adjacent surface. The panels (11) are connected to each other by linking edge portions of the flat surfaces (12a′) of the respective substrates (12) so that longitudinal directions of the respective rectangular display sections (13) are parallel to each other and so that the adjacent surface (12b′) is located on the back side of the substrate (12). In an image display section, pixels (50) are arranged in a matrix, and sub-pixels in each of the pixels (50) are aligned in a column direction of the matrix.
