Folding part 23 is used to support liquid crystal panel 01 and diaphragm 03.Backboard 2 provided in an embodiment of the present invention is molded by integral wrap direction,
Bent on the basis of with slab construction bottom plate 21, form the side plate 22 positioned at the surrounding of bottom plate 21；Side plate 22 continues
It is bent to form stepped kink 23.Because side plate 22 is located at the surrounding of bottom plate 21, thus, bottom plate 21 and side plate 22 surround top
Cavity 5 in the cavity structure of opening, i.e. accompanying drawing 3.Stepped kink 23 is located at the top of side plate 22, and stepped kink
23 are bent to form first step 231 from the top of side plate 22 to the direction of cavity 5, and from the end of first step 231 to bottom plate 21
Direction is bent to form second step 233.Due to stepped kink 23 from the top of side plate 22 to the direction of cavity 5 bend, thus,
Side plate 22 forms the structure type around stepped kink 23, and now side plate 22 forms the outermost Rotating fields of backboard 2, backboard 2
Regular integrated planar structure is seen as from formalness.
Because the gravity of the parts such as liquid crystal panel 01, diaphragm 03 and light guide plate 04 mainly acts on bottom plate 21 and side plate 22
On, thus when the angle between bottom plate 21 and side plate 22 is more than 90 °, the grade of liquid crystal panel 01 part can apply parallel to side plate 22
Horizontal applied force in bottom plate 21 and the vertical perpendicular to bottom plate 21.Side plate 22 is in horizontal applied force and perpendicular acting
Easily tilted in the presence of power to the direction of bottom plate 21, stepped kink 23 can not be supported by ultimately resulting in side plate 22, and backboard 2 occurs
Structure collapses.To prevent the recurring structure of backboard 2 from caving in, in embodiments of the present invention, side plate 22 is set perpendicular to bottom plate 21, so that
The grade of liquid crystal panel 01 part only applies the vertical perpendicular to bottom plate 21 to side plate 22.
Further, to make stepped kink 23 that there is higher support strength, each part in stepped kink 23
Preferred arrangement is：First step 231 and second step 233 are parallel to each other, and the first connecting plate 232 is perpendicular to second step
233.Now, the alternate hierarchic structure of the stepped transverse and longitudinal of kink 23 is more firm.Further, it is higher to have backboard 2
Support strength, first step 231 is parallel to bottom plate 21, and second step 233 is perpendicular to side plate 22.
In the embodiment of the present invention, stepped kink 23 includes first step 231, the first connecting plate 232 and second step
233.First step 231 is used to support liquid crystal panel 01.First connecting plate 232 is used to connect first step 231 and second step
233.Second step 233 is used to support diaphragm 03, specifically refer to accompanying drawing 3,4.
Specifically, liquid crystal panel 01 is the display unit of liquid crystal display device, including Polarizer, glass substrate and liquid crystal
Multiple parts such as material, thus there is larger weight.Again because the end of liquid crystal panel 01 is located at first step 231, thus
The middle part of liquid crystal panel 01 may deform because weight is larger.To enable first step 231 to support liquid crystal surface
Plate 01, and prevent liquid crystal panel 01 from deforming, first step 231 should have enough width h1.If but first step 231
Width h1 is wide, then causes the wider width of liquid crystal display device.The increase of liquid crystal display device width can cause production cost
Increase, while the visual experience of user can be also reduced, thus, the width h1 of first step 231 should have suitable width.Diaphragm
The problem of 03 weight is smaller, and second step 233 will not deform upon when supporting diaphragm 03, thus the width of second step 233
Degree h2 meets that diaphragm 03 can be supported.In embodiments of the present invention, on the basis of the width h2 of second step 233, preferably
The width h1 of first step 231 is set as 2-4 times of the width h2 of second step 233, to meet that first step 231 supports liquid crystal respectively
Panel 01, second step 233 support the width demand of diaphragm 03.
Because second step 233 is used to support diaphragm 03, therefore, to make energy between first step 231 and second step 233
Diaphragm 03 is enough placed, the spacing between first step 231 and second step 233 is more than or equal to the thickness of diaphragm 03.Specially：
Spacing between the upper surface of second step 233 and the lower surface of first step 231 is more than or equal to the thickness of diaphragm 03.Work as liquid crystal surface
When being additionally provided with miscellaneous part between plate 01 and diaphragm 03, the spacing between first step 231 and second step 233 is more than diaphragm 03
Thickness.When being not provided with miscellaneous part between liquid crystal panel 01 and diaphragm 03, between first step 231 and second step 233
Spacing can be equal to diaphragm 03 thickness.
In addition, stepped kink 23 is located at the inside of cavity 5, and certain space is occupied, if stepped kink 23
Spacing between bottom plate 21 is smaller, then should not set light guide plate 04.Therefore, for make on bottom plate 21 set light guide plate 04, second
Spacing between step 233 and bottom plate 21 is more than or equal to the thickness of light guide plate 04.More specifically, the following table of second step 233
Spacing between face and the upper surface of bottom plate 21 is more than or equal to the thickness of light guide plate 04.
In embodiments of the present invention, the fixed form of diaphragm 03 is that bolt twist-on or hangers mount.When diaphragm 03 passes through spiral shell
When bolt twist-on mode realizes fixed, it is bolted on second step 233 or on the first connecting plate 232.When diaphragm 03 is logical
Hangers mounting mode is crossed when realizing fixed, first connecting plate 232 that is set by of the position of diaphragm 03 is realized.That is the first connecting plate
