Abstract

An image display device includes: a display unit having a display panel and a support member supporting the display panel; a plurality of attaching members arranged on the support member; and a base plate opposing a back surface of the support member. The base plate includes a first opening part and a second opening part. The first opening part has an opening through which a fastening member passes, the fastening member fastening the base plate with a first attaching member. The second opening part has an opening into which a protruding part is inserted, the protruding part being provided to a second attaching member, the opening is larger than the protruding part as viewed from a protruding direction of the protruding part.

First claim

The invention claimed is:

1. An image display device, comprising:
a display unit including:
a display panel that displays an image on a front surface of the display panel, and
a support member opposing a back surface of the display panel and supporting the display panel;

a plurality of attaching members on the support member; and
a base plate opposing a back surface of the support member,
wherein the base plate includes:
a first opening part including an opening through which a fastening member passes, the fastening member fastening the base plate with a first attaching member that is one of the plurality of attaching members; and
a second opening part including an opening into which a protruding part is inserted, the protruding part being provided to a second attaching member that is another one of the plurality of attaching members, the opening of the second opening part being larger than the protruding part as viewed from a protruding direction of the protruding part, and
when the first attaching member supports the display unit, the inserting of the protruding part of the second attaching member into the opening larger than the protruding part as viewed from the protruding direction prevents the second attaching member from receiving load of the display unit.

2. The image display device according to claim 1 , wherein the second attaching member is arranged such that the protruding part is positioned not lower than a middle of the display unit in an up-down direction.

3. The image display device according to claim 1 , wherein two second attaching members each being the second attaching member are arranged side by side in a left-right direction on the back surface of the support member.

4. The image display device according to claim 1 , wherein the opening in the second opening part is longer in the up-down direction than in the left-right direction.

5. The image display device according to claim 1 , further comprising:
a bezel covering a lower end part of the front surface of the display panel.

6. The image display device according to claim 1 ,
wherein the first attaching member includes a first screw hole into which a first screw is screwed, the first screw being the fastening member, and
the second attaching member includes a second screw hole into which a second screw is screwed, the second screw being the protruding part, the second screw hole having a same inner diameter as an inner diameter of the first screw hole.

7. The image display device according to claim 1 ,
wherein the support member is a support plate opposing the back surface of the display panel, and
the plurality of attaching members are bonded to a back surface of the support plate.

8. The image display device according to claim 7 ,
wherein the display unit further includes:
a light guide plate located between the display panel and the support plate;
a light source part located at a position opposing a lower end surface of the light guide plate; and
a light-source support member supporting the light source part from below.

9. The image display device according to claim 1 ,
wherein the support member is a frame member attached to a peripheral edge of the back surface of the display panel, and
the plurality of attaching members are press fitted into or welded to the frame member.

10. The image display device according to claim 9 , wherein each of the plurality of attaching members is an outsert nut embedded in the frame member.

11. The image display device according to claim 10 , wherein the protruding part is a portion of the outsert nut that is the second attaching member, the portion protruding from the frame member.

12. The image display device according to claim 9 , further comprising
a back cover covering a part of a back surface of the base plate,
wherein the second opening part is located at a position in the base plate, the position being covered with the back cover in the base plate.

13. The image display device according to claim 1 , wherein the protruding part is a step part of a stepped screw, the stepped screw including a shaft part and the step part, the shaft part being screwed into a screw hole of the second attaching member, the step part being located in a foot of the shaft part.

14. The image display device according to claim 1 , wherein the opening larger than the protruding part as viewed from the protruding direction allows the protruding part to be inserted into the opening in the protruding direction.

15. An image display device, comprising:
a display unit including:
a display panel that displays an image on a front surface of the display panel, and
a support member opposing a back surface of the display panel and supporting the display panel;

a plurality of attaching members on the support member; and
a base plate opposing a back surface of the support member,
wherein the base plate includes:
a first opening part including an opening through which a fastening member passes, the fastening member fastening the base plate with a first attaching member that is one of the plurality of attaching members; and
a second opening part including an opening into which a protruding part is inserted, the protruding part being provided to a second attaching member that is another one of the plurality of attaching members, the opening of the second opening part being larger than the protruding part as viewed from a protruding direction of the protruding part to allow the protruding part to be inserted into the opening in the protruding direction.
