<P>PROBLEM TO BE SOLVED: To provide an attachment structure of a printed board in a display device which causes electromagnetic noise radiated from electronic components, a wiring pattern, and a substrate side surface less likely to leak to the exterior. <P>SOLUTION: A printed board 13 is attached on a metal chassis 11 to which a liquid crystal panel 12 is attached. Electronic components 14 are mounted only on one substrate surface 13a located on the side which faces the metal chassis 11. A ground plane, formed by copper foil and the like, is formed on an entire part of the other substrate surface 13b of the printed board 13 which is located on the opposite side of the metal chassis 11. The metal chassis 11 includes a step like conductive protruding part 11C composed of a first protruding part 11A and a second protruding part 11B. The first protruding part 11A has a frame like surface 11a which forms a frame like shape in a plane view. The second protruding part 11B protrudes enclosing an outer periphery of the frame like surface 11a, and an inner peripheral side surface 11b contacts with a side surface 13c of the printed board 13. <P>COPYRIGHT: (C)2013,JPO&INPIT |
