The display panel 20 is located on the front cabinet 30 by the holding part 12 of the locating member 10.

In this state, the ribs 14 of the locating member 10 partly formed in the shape of a lattice are in contact with the back surface of the display panel 20 to hold the display panel 20 on the front cabinet 30. Therefore, even if the display panel 20 has an irregular back surface, it is possible to prevent the warp of the base part 11 of the locating member 10 caused by force acting on the locating member 10 and the unsatisfactory pressing of the display panel 20 against the front cabinet 30.

Subsequently, other corners of the display panel 20 are located on the front cabinet 30 by the locating members 10. As shown in FIG. 12, collar screws 37 are screwed into the second bosses 36 to fix the display panel 20 to the front cabinet 30. Then, the rear cabinet 40 is fixed to the front cabinet 30 so as to cover the open rear end 31 of the front cabinet 30.

2. Second Embodiment

The first embodiment uses the locating members 10 for locating the display panel 20 on the front cabinet 30. The locating members 10 may be used for fixing the display panel 20 to the front cabinet 30. When the display panel 20 is a small one, such as a 15 in. display panel, the display panel 20 has a small weight.
