FIG. 6 is a rear view showing the display unit with the back cabinet of the liquid crystal display device removed, and FIG. 7 is a rear view showing the positional relationship between the display device main body and the cushioning material.
図６、図７に示すように、表示ユニット７の駆動回路ブロック６の回路基板が取り付けられるフレーム５は、表示ユニット７を正面視または背面視したときに、横長（上下の編が左右の辺より長い）長方形状である。このフレーム５の長辺側の上部周縁部の両端付近には、表示ユニット７がコーナー部の緩衝材２２により保持される部分に補強用の第１のビード部５ａがそれぞれ設けられている。また、これらの第１のビード部５ａの間には、第１のビード部５ａと分離した状態で補強用の第２のビード部５ｂが設けられている。第２のビード部５ｂは、表示ユニット７が中央部の緩衝材２４により保持される部分に設けられている。第１のビード部５ａと第２のビード部５ｂは、フレーム５の一部が背面側に膨出するようにフレーム５に絞り加工を施すことにより形成されている。また、本実施の形態における第１及び第２のビード部５ａ，５ｂは、表示ユニット７を正面視または背面視したときに、幅が概ね一定の細長い長方形状である。
As shown in FIGS. 6 and 7, the frame 5 to which the circuit board of the drive circuit block 6 of the display unit 7 is attached is horizontally long (the upper and lower knitting are on the left and right sides when the display unit 7 is viewed from the front or the back. Longer (rectangular). Near both ends of the upper peripheral portion on the long side of the frame 5, reinforcing first bead portions 5 a are provided at portions where the display unit 7 is held by the cushioning material 22 at the corner portion. Further, a reinforcing second bead portion 5b is provided between the first bead portions 5a in a state separated from the first bead portion 5a.

Alternatively, the first and second bead portions 5 a and 5 b may be formed only at the lower peripheral edge portion on the long side of the frame 5.
外装ケース８が狭額縁化されるに伴い、外装ケース８の周縁部の幅が狭くなって強度が低下する。また、バックキャビネット１０を表示ユニット７にバックキャビネット１０にねじ止めするための穴加工を行う必要があり、さらに強度が低下してしまう。
As the outer case 8 is narrowed, the width of the peripheral portion of the outer case 8 becomes narrower and the strength decreases. Moreover, it is necessary to perform hole processing for screwing the back cabinet 10 to the display unit 7 to the back cabinet 10, and the strength is further reduced.
しかし、本開示においては、表示ユニット７のフレーム５の長辺側周縁部において、前記コーナー部の緩衝材２２により保持される部分に補強用の第１のビード部５ａを設けるとともに、前記第１のビード部５ａの間にこの第１のビード部５ａと分離した状態で補強用の第２のビード部５ｂを設けたことにより、フレーム５の剛性が向上する。そのため、外装ケース８が狭額縁化された場合であっても、表示装置本体１を変形させようとする応力に対して強度を向上させることができ、この結果、輸送途中で表示装置本体１が破損してしまうのを防止することができる。
However, in the present disclosure, the first bead portion 5a for reinforcement is provided in a portion held by the cushioning material 22 of the corner portion in the peripheral portion on the long side of the frame 5 of the display unit 7, and the first By providing the second bead portion 5b for reinforcement in a state separated from the first bead portion 5a between the bead portions 5a, the rigidity of the frame 5 is improved. For this reason, even when the outer case 8 is narrowed, the strength can be improved against the stress that causes the display device body 1 to be deformed. As a result, the display device body 1 can be improved during transportation. It can be prevented from being damaged.
このように本開示においては、薄型表示装置において、より一層の薄型化が図られるとともに、狭額縁デザインの採用により、機械的な強度が低下しても、輸送時に受ける機械的衝撃などによる破損を防ぐことができるという効果が得られる。
As described above, in the present disclosure, the thin display device can be further thinned, and even if the mechanical strength is reduced due to the adoption of the narrow frame design, the thin display device is not damaged due to a mechanical shock or the like that is received during transportation. The effect that it can prevent is acquired.
