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.

Abstract: There is disclosed a flat panel display device which is thin in thickness, light in weight, and improved in durability. A liquid crystal display panel 30 and a surface light source unit 50 are held between a base enclosure 64 of a housing 22 and a surface cover member 60. The display panel 30 is connected to rotatable support members 26 which rotatably support the display panel 30. The surface light source unit 50 includes a tube-like light source 53, a reflector 54 and an inverter circuit 80 to drive the light source 53 which are disposed close to the support members 26 in the enclosure 64. The surface light source unit 50 further includes a light guide 52 which is gradually thinner in thickness from the side of the support member 26 to its opposite side. The enclosure 64 further includes a bottom plate 68 which is also gradually thinner in thickness from the side of the support member 26 to its opposite side.
