[0002]

2. Description of the Related Art Plasma display panels (hereinafter referred to as P
FIG. 1 shows a display device using a DP panel or the like.
As shown in the figure, the depth is thin relative to the size of the display screen,
And it is characterized by being lightweight. A housing 1 of the display device includes a front cover 2 made of a synthetic resin having an opening on the front surface, and a rear cover 3 made of a metal. FIG. 4 shows the inside of the housing 1 in an AA cross section. The PDP panel 4 is fixed to a metal reinforcing plate 22 via a plurality of spacers 21 by screws 23 on the back surface thereof. I have. On the other hand, front cover 2
A plurality of bosses 24 are provided upright on the inner surface of the front edge of the boss 24.
Is fixed by screws 26.

[0003]

By the way, the above-mentioned display device not only requires a large number of screws for assembly, but also has a problem in that workability is poor because screws have to be screwed from four sides and a back surface. There is. Accordingly, it is an object of the present invention to provide a display device in which the amount of screws used can be reduced and assembly can be performed more easily.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems, and a display panel is provided on a side of an opening in a housing including a front cover having an opening on a front surface and a rear cover. In fixing
A plurality of protruding pieces having insertion holes A are provided on a peripheral edge of a metal plate constituting the display panel, and a plurality of bosses A for supporting the protruding pieces are provided on an inner surface of a front edge of the front cover. A frame provided with a plurality of insertion holes B corresponding to the insertion holes A and a plurality of bosses B facing the rear cover is overlapped with the projecting piece supported by the projection piece and screwed together, and the rear cover is fixed to the boss. B was screwed.

[0005]

According to the above construction, a plurality of bosses A provided on the inner surface of the front edge of the front cover are provided with a projecting piece extending from a metal plate constituting a display panel and a frame formed separately. Boss B provided on the frame body
The display device can be completed by screwing the rear cover to the panel.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows an appearance of a display device. The housing 1 includes a front cover 2 having an open front surface and made of resin such as ABS, and a rear cover 3 made of metal. As shown in FIGS. 2 and 3, a display panel (PDP panel) 4 provided in the housing 1 includes a filter 5 made of acrylic or the like provided on the front surface, a glass plate 6 filled with a predetermined gas, and a A metal plate (aluminum plate) 7 provided behind the glass plate 6;
It comprises a printed board 9 provided behind the metal plate 7 via a plurality of spacers 8, a plurality of screws 10 for mounting the printed board 9, and the like. A protruding piece 12 is provided.

On the other hand, a plurality of bosses A for supporting the projecting piece 12 on the PDP panel 4 side are provided on the inner surface of the front edge of the front cover 2.
13 are provided. Reference numeral 14 denotes a frame formed so as to surround the PDP panel 4 so as to overlap the protruding piece 12. The frame 14 has an insertion hole A11 formed in the protruding piece 12 and a boss A13 on the front panel 2 side. Are alternately provided with bosses B16 for attaching the rear cover 3 to the insertion holes B15 corresponding to. When assembling, PD
The filter 5 of the P panel 4 is connected to the opening 1 of the front cover 2.
7, the boss A13 is aligned with the projecting piece 12, then the insertion hole A11 of the projecting piece 12 is aligned with the insertion hole B15 on the frame 14, and the screw 18 is inserted into the boss A1.
Fix to 3. At the stage when the eight peripheral parts have been screwed in this way, the front cover 2 is covered with the rear cover 3, and the rear cover 3 is attached to the boss B provided on the frame 4.
16 is fixed using screws 19, and the assembly is completed. Although not shown, by interposing a buffer member formed, for example, in a ring shape between the boss A13 and the protruding piece 12, it is possible to reduce the impact on the PDP panel 4 generated during transportation or the like. .

[0008]

According to the display device having the components described above, the PDP panel and the rear cover can be attached from one side, so that the workability is improved and the number of components required for the assembly is reduced, thereby increasing the cost. Will also be advantageous.
