  • Patent number: 6424391
    Abstract: A flat-panel display device is provided, that does not allow deformation due to fastening forces of a male screw even despite a gap which is created by a dimensional tolerance or the like between a bezel disposed to a display cell and a housing. Female screws 26 formed in a bezel 22 are deformable in a direction toward an inner surface of the housing 25. The fastening force of male screws 27, which penetrates a side wall portion 25a of the housing 25 in which the display cell 11 is housed and a side-surface portion 24 of the bezel 22 and which engages with the female screws 26 formed in the bezel 22, does not cause large deformation.
