An object of the invention is to form a projecting image of smooth image quality inconspicuous in a joint in a stable state. In an exemplary acoustically anti-guiding fiber, a suitable cladding size for ant guiding fibers occurs wherein the cladding size is determined such that the net material dampening in the cladding is large enough to dampen acoustic waves. Each pixel includes a TFT and a pixel electrode, wherein the pixel electrode is connected to one of the scan lines and one of the data lines through the TFT.
