A display device includes a printed circuit board having a plurality of light emitting members, an anti-moir\xe9 member spaced away from the plurality of light emitting members at about a first distance, and a frame member receiving the PCB such that the PCB is interposed between the anti-moir\xe9 and the frame member. A layer of conductive material having a controlled outline is disposed to provide artifact edges of the conductive material that resemble an operable device when in fact the device is not operable. The preparation-complete detector includes first and second frame memory groups to sequentially store a divided signal for a plurality of frames. 02 to 3 mass % in terms of Fe to 100 mass % of the sintered body. In a wet-laid inclined machine, the fibrillated fibers are formed into a continuous web and then the web or portions of it are subjected to a temperature treatment to make the web electrically conducting by carbonizinggraphitizing the web through heating.
