Accordingly, the
  • the mounting of the filter 13 to the panel holder members 14 a , 14 b , 14 c , 14 d is not carried out directly by using screws but is carried out by causing the filter 13 to be interposedly held between the panel holder members 14 a , 14 b , 14 c , 14 d and the filter holder members 15 a , 15 b , 15 c , 15 d , so that the number of screws to be used may be a necessary minimum and can be considerably reduced.
  • the cabinet 12 and the panel holder device 14 are engaged with each other at the upper end portion of the view area, and screw-fastened to each other at the lower portions thereof only, so that the number of screws to be required can be also reduced.
  • the screw-fastening operations can be all carried out from the above side, so that it is possible to considerably improve efficiency of the screw-fastening operations, as compared to the related screw-fastening operations which are necessarily carried out from lateral, forward and rearward sides.
  • a distance between the plasma display panel 11 e and the filter 13 can be defined at the mounting position of the panel holder device 14 and the filter holder device 15 , such spacers as required in the related art are not required.
  • the mounting of the cabinet 12 and the panel holder device 14 is carried out at the upper end portions thereof by means of the engaging construction as discussed above, so that in a case where the cabinet 12 is required to be separated from the panel holder device 14 at the time of any adjusting work required to be performed at the back of the plasma television 11 and at the time of maintenance work, even if the screw securing the lower end portion of the cabinet 12 is loosened, the upper end portion of the cabinet 12 is engaged with the panel holder device 14 , thus preventing the cabinet 12 from being completely removed from the panel holder device 14 .
  • the separation of the cabinet 12 from the panel holder device 14 can be performed by only loosening the screw securing the lower end portion of the cabinet 12 , it is possible to improve efficiency of the work.
  • the present invention is not limited to the case and can be applied to other flat display panels, such as a liquid crystal display panel, an organic EL and the like.
  • the plasma display panel having a panel size of 37 inch or more is employed is discussed above, this is merely an example of the present invention and the panel size is not limited to 37 inch or more. Incidentally, the above-mentioned effects obtained by the present invention are remarkably produced in a case where a display panel which is large-sized and weighty is employed.
  • the present invention is not limited to such shapes.
  • the filter which is carried on the cabinet carried in a standing up state on the line, from the above side can be interposedly held and fixed by the panel holder and the filter holder, and the flat display panel which is also carried from the above side can be fixed, the shapes of the panel holder and the filter holder may be suitably varied.
  • the panel holder members arranged at the upper and lower sides of the view area and the panel holder members arranged at the left and right sides of the view area are different from each other in the shape of the cross-section, and the filter holder members arranged at the upper and lower sides of the view area and the filter holder members arranged at the left and right sides of the view area are also different from each other in the shape of the cross-section.
  • the upper and lower panel holder members and the left and right panel holder members are not necessarily formed so as to have the cross-section of different shapes each other, and the upper and lower filter holder members and the left and right filter holder members are not necessarily formed so as to have the cross-section of different shapes each other. They may be formed so as to have the same shape in cross-section.
  • the screw-fastening operations can be all carried out from the above side in the illustrated embodiment, the present invention is not necessarily limited to this.
  • the mounting operations can be carried out on the production line, the screw-fastening operations may be carried out from, for example, the lateral directions. In this case, work efficiency may be slightly lowered as compared to the case where the screw-fastening operations are carried out from the above side but other effects are still obtained.
  • the engaging structure between the upper end portion of the view area of the cabinet and the upper panel holder member may be omitted.
  • a fixing structure by screw-fastening may be employed. In this case, when separating operation of the cabinet is carried out, the effect of preventing of the cabinet from being completely removed from the panel holder device is not obtained, but other effects can be obtained.
