Description

  The present invention relates to a support member and an image display device including the support member.

Generally, a display device is a module in which a display panel, a light source that illuminates the display panel, and a backlight unit that includes optical sheets that collect and uniformize light from the light source are integrated with a frame-shaped holder. Known to.
Since the display panel is manufactured by cutting glass, there may be burrs on the end face. For this reason, when the display panel is deformed in the thickness direction due to environmental changes such as humidity, the display panel may be caught at the lower part of the holder. As a result, stress is generated in the display panel, which may cause display unevenness.

  There is a need for a holder that does not cause stress in the display panel when the display panel is deformed. For example, Patent Document 1 describes that the lower end portion of the display panel is held by an elastic cover such as rubber or resin that is provided below the frame-shaped holder. The cover has a narrow structure in which the upper part is narrow and the lower part is wide, and the display panel is held by sandwiching the display panel with an upper part of the cover.

  Also, the lower part of the cover is wide, and when the display panel is deformed in the thickness direction due to environmental changes such as humidity, the position of the end of the display panel is shifted according to the deformation. Yes. Further, the surface inside the cover is smooth, and it is easy to slip when the position of the end of the display panel shifts.

JP 2010-204357 A

However, when the display panel is distorted, the catch cannot be sufficiently prevented, and stress is applied to the display panel.
For example, the entire end surface of the display panel is in contact with a cover that holds the display panel. Furthermore, since the weight of the display panel is added, the frictional sliding resistance generated on the contact surface between the display panel and the cover increases.

For this reason, even if the surface inside the cover is smooth, when the display panel is distorted, it is not possible to sufficiently prevent the catch and stress is applied to the display panel. As a result, the display characteristics of the display panel may change and display unevenness may occur.
Accordingly, an object of the present invention is to provide a method for supporting a display panel without causing stress even when the display panel is distorted.

  The first aspect of the present invention is a support member having a fixed portion fixed to the lower end portion of the display panel and a shaft portion rotatably inserted into a hole provided in the frame-shaped panel holder, Provided is a support member that supports the display panel in a state in which the shaft portion is inserted into the hole portion.

  A second aspect of the present invention provides an image display device comprising a display panel, a frame-like panel holder, and the support member described in the first aspect.

  According to the present invention, even when distortion occurs in the display panel, the display panel can be supported without causing stress.

For example, the present invention may be appropriately modified or changed depending on the configuration of the apparatus to which the present invention is applied and various conditions.

<Example 1>
Hereinafter, a first embodiment of the present invention will be described in detail with reference to FIGS.
FIG. 5 is an exploded perspective view of the display module. The backlight unit 24 includes optical sheets 20, a reflection sheet 21, and an LED substrate 22. The front holder 1 is disposed on the display surface side of the liquid crystal panel 2, and the optical sheets 20, the reflection sheet 21, and the LED substrate 22 are disposed in this order on the rear surface side of the liquid crystal panel 2.
Further, the LEDs 22a are arranged on the LED substrate 22 in a plane. The frame-shaped panel holder 3 and the back case 23 integrally form a box shape, and hold the LED substrate 22, the optical sheets 20, and the liquid crystal panel 2 at regular intervals.
The display module according to the first embodiment is an example of an image display device.

  The liquid crystal panel 2 is held in a sandwiched state between the front holder 1 on the front side and the panel holder 3 on the back side. Further, a cushioning material may be provided between the front holder 1 and the liquid crystal panel 2 and between the panel holder 3 and the liquid crystal panel 2 so as to hold the liquid crystal panel 2 softly. However, the lower side of the liquid crystal panel 2 is supported by a support member 4 described later.

FIG. 1 is a front view of the display module with the front holder 1 removed. In this embodiment, the driver board 2a is disposed above the module. A driver substrate 2a is integrally formed on the liquid crystal panel 2 via a plurality of FPCs (flexible substrates).
The panel holder 3 is a frame-shaped holder corresponding to the outer periphery of the liquid crystal panel 2 so that the liquid crystal panel 2 can be fitted therein. On the lower side of the panel holder 3, there are a protruding portion 3a and a protruding portion 3b protruding upward. Although details will be described later, the support member 4 is provided at a position that divides the horizontal width of the liquid crystal panel 2 into four equal parts, and a protruding portion 3 a and a protruding portion 3 b that protrude upward are formed at positions corresponding to these. In addition, the upper side of the panel holder 3 has two protrusions 3d protruding downward.

Further, the lower side protrusion 3a and the upper side protrusion 3d, and the lower side protrusion 3b and the upper side protrusion 3d are provided at positions facing each other. Further, two protrusions 3c protruding leftward on the right side of the panel holder 3 and two protrusions 3c protruding rightward on the left side are provided at positions facing each other.
The protrusion 3a, the protrusion 3b, the protrusion 3c, and the protrusion 3d serve as a reference for positioning the liquid crystal panel 2, and the liquid crystal panel 2 is positioned by these. In addition, the protrusion 3 a, the protrusion 3 b, the protrusion 3 c, and the protrusion 3 d are arranged with a predetermined gap from the outer peripheral portion of the liquid crystal panel 2 so as not to prevent deformation of the liquid crystal panel 2. The liquid crystal panel 2 is an example of a display panel.

The support member 4 includes a sandwiching portion 4 a that sandwiches an end portion of the liquid crystal panel 2, a body portion 4 b, and a shaft portion 4 c that projects in a direction parallel to the surface of the liquid crystal panel 2 from the peripheral portion of the liquid crystal panel 2. The holding portion 4a of the support member 4 has a shape that can be attached to the end portion of the liquid crystal panel 2, and is formed on the opposite side of the shaft portion 4c via the body portion 4b.
Moreover, the clamping part 4a may be fixed by, for example, an adhesive or the like in a state where the lower end part of the liquid crystal panel 2 is clamped. On the other hand, the shaft portion 4c of the support member 4 has a cylindrical body portion.
In addition, the clamping part 4a fixed in the state clamped by the lower end part of the liquid crystal panel 2 is an example of the fixing part fixed to the lower end part of a display panel.

Moreover, the hole 3e is provided in the protrusion part 3a and the protrusion part 3b of the lower end part of the panel holder 3, respectively. Specifically, when the liquid crystal panel 2 is fitted at a position positioned by the protrusion 3a, the protrusion 3b, the protrusion 3c, and the protrusion 3d, the panel is positioned so that the protrusion 3a and the protrusion 3b can be inserted. Each hole 3e of the holder 3 is arranged.
The shaft portion 4c of the support member 4 has a shape that can be inserted into the hole 3e. Here, when the shaft portion 4c is inserted into each hole portion 3e, the liquid crystal panel 2 is moved downward by its own weight, so that the tip portion 4d of each shaft portion 4c is in contact with the bottom portion of each hole portion 3e. It becomes.
Below, the structure around the panel holder 3 and the support member 4 is demonstrated in detail.

FIG. 2 is a diagram illustrating a first cross-sectional view around the support member. 2 is a cross-sectional view corresponding to CC in FIG. Here, in FIG. 2, the front holder 1 is also illustrated.
As described above, on the back side of the liquid crystal panel 2 (opposite the display surface), the optical sheets 20 and the LED substrate 22 are held in a predetermined positional relationship by the back cover 23 and the panel holder 3.

The support member 4 includes a cylindrical shaft portion 4c on the opposite side of the sandwiching portion 4a, and the tip portion 4d of the shaft portion 4c has a sharp conical shape. Further, the shaft portion 4c has a cylindrical body portion and a smooth surface. The shaft portion 4 c of the support member 4 is inserted into the hole portion 3 e provided in the projection portion 3 a of the panel holder 3. The shaft portion 4c is rotatable around the central axis (the chain line in FIG. 2) of the body portion of the shaft portion 4c. The alternate long and short dash line is also shown in FIG.
The surface of the hole 3e is processed smoothly.

As described above, the hole 3e of the panel holder 3 and the shaft 4c of the support member 4 are each cylindrical, and each surface is smooth, so that resistance during rotation is very small. Further, since the tip 4d of the support member 4 has a sharp conical shape, the contact area when the shaft 4c is inserted into the hole 3e is reduced, and the resistance during rotation is further reduced.

The panel holder 3 includes a flange 3 f and a front holder 1, and the flange 3 f and the front holder 1 are arranged at positions that sandwich the peripheral edge of the liquid crystal panel 2. Specifically, the flange 3 f is provided close to the back side of the liquid crystal panel 2 and parallel to the liquid crystal panel 2. Further, the front holder 1 is provided close to the front side of the liquid crystal panel 2 and parallel to the liquid crystal panel 2.
Further, the peripheral edge portion of the liquid crystal panel 2 is softly held between the cushion 6 fixed to the flange 3 f and the cushion 5 fixed to the front holder 1.
For this reason, even if the liquid crystal panel 2 is warped, the warp can be absorbed by the elastic compression of the cushion 5 and the cushion 6.

FIG. 3A and FIG. 3B show the 1st figure for demonstrating the shape of the axial part 4c and the hole 3e. 3A is a cross-sectional view corresponding to the position A in FIG. 4A and 4B show a second view for explaining the shapes of the shaft portion 4c and the hole portion 3e. 4A is a cross-sectional view corresponding to the position B in FIG. 3A and 4A correspond to the DD cross section of FIG.
As shown in FIG. 3A, the hole 3 e of the panel holder 3 has a diameter that does not hinder the rotational movement of the support member 4. That is, the hole 3 e of the panel holder 3 has a diameter that is slightly larger than the diameter of the cylindrical shaft portion 4 c of the support member 4.

FIG. 3B is a cross-sectional view corresponding to a two-dot chain line portion viewed from above when the shaft portion 4c is inserted into the hole 3e. That is, FIG. 3B is a cross-sectional view taken along the alternate long and two short dashes line in the direction of the arrow in FIG. 3A. It can be seen that the shaft portion 4c and the hole portion 3e both have a circular cross section, and the diameter of the hole portion 3e is slightly larger than the diameter of the shaft portion 4c.
Thus, the panel holder 3 can accurately position the liquid crystal panel 2 at a predetermined position.

On the other hand, in FIG. 4A, the hole 3 e of the panel holder 3 is a long hole having a length slightly larger than the diameter of the shaft portion 4 c of the support member 4 with respect to the long side direction of the liquid crystal panel 2. For this reason, as shown to FIG. 4A, a clearance gap exists between the axial part 4c and the hole 3e.
FIG. 4B is a cross-sectional view corresponding to the portion of the two-dot chain line viewed from the direction in which the shaft portion 4 c of the support member 4 is inserted into the hole 3 e of the panel holder 3. That is, FIG. 4B is a cross-sectional view of a portion indicated by a two-dot chain line in the direction of the arrow in FIG. As shown in FIG. 4B, the hole 3e has a longer length in the direction of the long side of the liquid crystal panel 2, and the shaft portion 4c is movable along the direction of the long side of the liquid crystal panel 2 (the direction of the arrow). is there.

On the other hand, as shown in FIG. 4B, the hole 3e has a length in the direction perpendicular to the long side of the liquid crystal panel 2 that is slightly larger than the diameter of the shaft 4c, and the shaft 4c, the hole 3e, There is almost no gap between them. For this reason, the shaft portion 4 c does not move in a direction perpendicular to the long side of the liquid crystal panel 2.
In this way, by making one of the holes 3e into a long hole, variations in the dimensions of the liquid crystal panel 2 can be absorbed. Further, as shown in FIG. 4B, the shaft portion 4c can move in the elongated hole portion 3e according to the deformation of the liquid crystal panel 2, so that the liquid crystal panel 2 generated when the liquid crystal panel 2 is deformed is removed. The effect of suppressing stress can also be obtained.

Next, a mechanism for absorbing deformation of the liquid crystal panel 2 will be described.
6A and 6B are diagrams for explaining a modification of the liquid crystal panel 2. FIG. 6A is a front view of the display module. FIG. 6B is a diagram illustrating deformation of the liquid crystal panel 2 when the liquid crystal panel 2 deformed according to the environment is viewed from below. It is assumed that the front holder 1 is on the upper side (in the direction of the arrow) in FIG. 6B and the backlight unit 24 is on the lower side.
The liquid crystal panel 2 is warped as shown in FIG. 6B due to changes in temperature and humidity. What is remarkable is the influence of humidity, which is caused by the moisture absorption of the polarizing film on the panel surface.

For example, in a high humidity environment, as indicated by the dotted line 10a, the central portion of the liquid crystal panel 2 is convex downward (backlight unit side (opposite direction of the arrow)), and the periphery of the liquid crystal panel 2 is upward. Let's warp. In a low-humidity environment, as indicated by the alternate long and short dash line 10b, the central portion of the liquid crystal panel 2 is convex upward (surface side (the direction of the arrow)), and the peripheral edge of the liquid crystal panel 2 warps downward. When such a warp occurs, the amount of displacement in the thickness direction of the liquid crystal panel 2 becomes substantially zero at the intersection of the alternate long and short dash line in FIG. 6B.
6B corresponds to the alternate long and short dash line in FIG. 6A that divides the panel width of the liquid crystal panel 2 into four (positions 1/4 from the right and left sides of the liquid crystal panel 2). Therefore, as shown in FIG. 6A, when the liquid crystal panel 2 is deformed due to a change in environment by providing the support member 4 at a position where the panel width of the liquid crystal panel 2 is divided into four equal parts or in the vicinity of the position divided into four equal parts The stress applied to the liquid crystal panel 2 can be minimized. In other words, among the long sides located on the lower side when the liquid crystal panel 2 is used, it corresponds to a position corresponding to a quarter length from the left of the long side and a length corresponding to a quarter length from the left of the long side. It can be said that the support member 4 is provided at the position to be operated. Note that the one-dot chain line in FIG. 6A corresponds to the one-dot chain line in FIG. 6B. 6B corresponds to a position at which the liquid crystal panel 2 is divided into two in the vertical direction.

  FIG. 7 is a diagram for explaining the relationship between the liquid crystal panel 2 and the panel holder 3. FIG. 7 corresponds to the perspective view of FIG. The support member 4 is fixed at a position where the displacement amount of the liquid crystal panel 2 described above is substantially zero. By providing the support member 4 at such a position, as shown in FIG. 7, when the liquid crystal panel 2 is warped and deformed, the shaft portion 4 c of the support member 4 rotates according to the deformation of the liquid crystal panel 2. I understand that.

Below, the effect in Example 1 compared with a prior art is demonstrated.
FIG. 12 is an exploded perspective view of a conventional display module. In the display module, the front holder 100 is arranged on the front side of the liquid crystal panel 200, and the optical sheets 400, the reflection sheet 500, and the LED 600a are arranged in this order on the back side.

  In addition, a plurality of ribs 301 are provided around the liquid crystal panel 200 to be positioned with respect to the plane direction of the liquid crystal panel 200 on the front side (front holder 100 side) of the frame-shaped holder 300. Each rib 301 is disposed with a gap so as to absorb the variation in dimensions of the liquid crystal panel 200. Further, the lower end portion of the liquid crystal display panel 200 is held by a cover 201 described later.

  FIG. 13 is a cross-sectional perspective view of the prior art. The liquid crystal display panel 200 is sandwiched between an elastic body 302 disposed on the upper side of the holder 300 and an elastic body 101 disposed on the back side of the holder 100. The lower end of the liquid crystal display panel 200 is covered with a cover 201.

  Since the weight of the liquid crystal display panel 200 is applied to the cover 201, it is not possible to sufficiently prevent the end of the liquid crystal display panel 200 from being caught when the liquid crystal display panel 200 is deformed. For this reason, stress is applied to the liquid crystal display panel 200, and a change in the alignment of the liquid crystal occurs, resulting in a change in display characteristics, resulting in display unevenness.

On the other hand, in Example 1, the lower end portion of the liquid crystal panel 2 is supported by the support member 4, and the support member 4 is freely rotated according to the deformation of the liquid crystal panel 2. The rotation loss of the support member 4 is extremely small compared to the frictional resistance when the friction surface slides linearly as in the prior art. As described above, since the support member 4 supports the liquid crystal panel 2 by a method in which stress is hardly generated, it is possible to prevent the image quality from being deteriorated by the stress when the liquid crystal panel 2 is deformed.

<Example 2>
FIG. 8 is a diagram showing a second cross-sectional view around the support member 7. The shape of the sandwiching portion 7 a of the support member 7 is the same as that of the first embodiment, and the sandwiching portion 7 a sandwiches the lower end portion of the liquid crystal panel 2. On the other hand, the opposite side of the holding portion 7a of the support member 7 is a hole portion 7c unlike the first embodiment. The hole 7c has a cylindrical shape, for example.

The support shaft 9 has a shaft portion 9a and a locking portion 9b. The trunk portion of the shaft portion 9a is cylindrical, and the tip portion 9c is conical and pointed. Moreover, the latching | locking part 9b exists in the other side of the front-end | tip part 9c. For example, the locking portion 9b has a diameter larger than the diameter of the shaft portion 9a. When the shaft portion 9a is inserted into the through hole 8a provided in the panel holder 8, the support shaft 9 is moved to the panel holder by the locking portion 9b. 8 is locked. The support shaft 9 may be fixed to the through hole 8a of the panel holder 8, for example, with a screw (not shown). Moreover, you may adhere | attach the axial part 9a near the latching | locking part 9b, and the through-hole 8a with an adhesive material.
Thereby, the support shaft 9 is fixed in a state of protruding in the direction of the lower end portion of the liquid crystal panel 2. In addition, the support member 7 of Example 2 is attached to the same position (position of the dashed-dotted line of FIG. 6A or FIG. 6B) as the support member 4 of Example 1 in the liquid crystal panel 2. FIG.

The shaft portion 9a of the support shaft 9 is, for example, cylindrical and has a diameter that is slightly smaller than the diameter of the hole portion 7c of the support member 7 and can be inserted into the hole portion 7c of the support member 7. Moreover, the front-end | tip part 9c of the support shaft 9 is sharp, for example, is cone shape. Here, when the shaft portion 9 a of the support shaft 9 is inserted into the hole portion 7 c of the support member 7, the liquid crystal panel 2 is moved downward by its own weight, so that the shaft portion 9 a of the support shaft 9 is the hole of the support member 7. It will be in the state contact | abutted to the bottom part of the part 7c. Since the tip end portion 9c of the support shaft 9 has a conical shape, the range in which the shaft portion 9a and the hole portion 7c abut is small.
Further, the surfaces of the shaft portion 9a and the hole portion 7c are smooth.
Thus, the shaft portion 9a of the support shaft 9 has a cylindrical shape that can be inserted into the hole portion 7c of the support member 7, and the tip end portion 9c of the support shaft 9 has a conical shape. Can be reduced.

Of the two support members 7 installed in the liquid crystal panel 2, the hole 7 c of one of the support members 7 has a cylindrical shape corresponding to the shape of the shaft portion 9 a of the support shaft 9, so that the liquid crystal panel 2 can be accurately Can be positioned.
Further, regarding the hole 7c of the other support member 7, the length in the direction of the long side of the liquid crystal panel 2 is larger than the diameter of the shaft portion 9a, and the length in the direction perpendicular to the long side of the liquid crystal panel 2 is the axis. It is a slot that is slightly larger than the diameter of the portion 4c.
Therefore, the shaft portion 9a is movable along the direction of the long side of the liquid crystal panel 2 when the liquid crystal panel 2 is deformed. Thereby, the effect which suppresses the stress to the liquid crystal panel 2 which generate | occur | produces when the liquid crystal panel 2 deform | transforms is acquired.

(effect)
In the first embodiment, the support member 4 is formed with the shaft portion 4c protruding. For this reason, when the liquid crystal panel 2 to which the support member 4 is fixed is incorporated into the panel holder 3, this part becomes an obstacle, and work such as partly dividing the panel holder 3 is required.
On the other hand, according to the second embodiment, it is not necessary to disassemble the panel holder 8 because the support shaft 9 may be inserted after the panel 2 to which the support member 7 is fixed is directly assembled in the panel holder 8. Therefore, the effect that the number of assembly steps can be reduced is obtained.

Further, the support member 7, the support shaft 9, and the front holder 1 may be formed of a conductive material such as a metal material, and electromagnetic noise generated in the liquid crystal panel 2 may be conducted to the front holder 1. Thereby, the electromagnetic noise radiated from the liquid crystal panel 2 can be effectively grounded from the front holder 1.
Specifically, the front holder 1 is connected to a ground (not shown) as a mechanical ground, and a transparent conductive film is partially exposed at the lower end of the liquid crystal panel 2. In this case, the support member 7 can efficiently release electromagnetic noise to the mechanical ground via the support shaft 9 and the front holder 1 by sandwiching the transparent conductive film portion with the sandwiching portion 7a.

<Example 3>
FIG. 9 is a diagram showing a third cross-sectional view around the support member. In the third embodiment, the tip end portion 11d has a hemispherical shaft portion 11c, and the shape of the shaft portion is different from that of the first embodiment. Further, the surface of the tip 11d is smooth.
Further, the panel holder 10 is different from the first embodiment in that a hemispherical recess 10c is provided. The radius of the recessed part 10c of the panel holder 10 is larger than the radius of the shaft part 11c. Moreover, the surface of the recessed part 10c is smooth.
In addition, the clamping part 11a of the support member 11 has the same structure as the clamping part 4a of the support member 4 of Example 1. Moreover, the panel holder 10 has the same structure as the panel holder 3 of Example 1 except that the hemispherical recess 10c is provided.

  When the shaft portion of the support member 11 is placed in the concave portion 10 c of the panel holder 10 with the end portion of the liquid crystal panel 2 being sandwiched by the sandwiching portion of the support member 11 as shown in FIG. The part is centered at the center of the recess 10c. That is, the tip 11d of the support member 11 is placed at the center of the recess 10c, and only the tip 11d contacts the recess 10c. Therefore, even if compared with Example 1 and Example 2, the contact area of the supporting member 11 and the panel holder 10- is small.

  Of the recesses 10c of the two panel holders 10, the shape of the recess 10c of one panel holder 10 may be hemispherical, and the shape of the other recess 10c may be a long hole. The diameter of the other recess 10 c is increased in the direction of the long side of the liquid crystal panel 2. Thereby, when the liquid crystal panel 2 is deformed, the shaft portion 11c can move in the elongated hole along the direction of the long side of the liquid crystal panel 2.

(effect)
As described above, since the shaft portion of the support member 11 is centered at the center of the recess 10 c of the panel holder 10, the liquid crystal panel 2 can be positioned in the panel holder 10.
Further, by making the recess 10c of the panel holder 10 into a long hole having a diameter corresponding to the direction of the long side of the liquid crystal panel 2, it is possible to absorb variations in dimensions of the liquid crystal panel 2 and the like. Moreover, the effect which suppresses the stress to the liquid crystal panel 2 which generate | occur | produces when the liquid crystal panel 2 deform | transforms is also acquired.
Further, even when compared with Example 1 and Example 2, the contact area between the shaft portion of the support member 11 and the recess of the panel holder 10 is further smaller, so that the resistance when the support member 11 rotates is further reduced. can do.

<Example 4>
FIG. 10 is a diagram illustrating a fourth cross-sectional view around the support member. In the fourth embodiment, a deformable elastic portion 12a having a small elastic coefficient is formed in the body portion 12b between the sandwiching portion 12a and the shaft portion 12c of the support member 12. The elastic portion 12a is deformed according to the deformation of the liquid crystal panel 2 when the liquid crystal panel 2 is deformed by an external force, and has a hardness that does not hinder the rotation when the support member 12 rotates. The material of the elastic part 12a is rubber or the like.
In addition, since the shape of the clamping part 12a and the axial part 12c of the support member 12 is the same as that of Example 1, description is abbreviate | omitted.

FIG. 11 is a diagram illustrating a fifth cross-sectional view around the support member. FIG. 11 shows a state where the elastic portion 12a is deformed when the liquid crystal panel 2 is deformed when a portion other than the center of the liquid crystal panel 2 is pushed from the front by an external force or the like.
Here, FIG. 6A will be described by applying it to the third embodiment. For example, in FIG. 6A, when the vicinity of the center of the liquid crystal panel 2 is pushed from the front by an external force, the support member 12 rotates according to the deformation of the liquid crystal panel 2. On the other hand, when a portion other than the center of the liquid crystal panel 2 in FIG. 6A is pushed from the front by an external force, the elastic portion 12a is deformed as shown in FIG.

(effect)
Thus, even when a portion other than the center of the liquid crystal panel 2 is pressed, the stress generated in the liquid crystal panel 2 can be suppressed.
Further, after the external force is removed, the elastic portion 12a can return the liquid crystal panel 2 to the original position by the elastic force. Furthermore, the elastic portion 12a can also obtain an action of weakening external force and impact on the liquid crystal panel 2.

(Other examples)
In the above embodiment, the application to the liquid crystal display panel has been described. However, the above embodiment can be applied to other display panels such as a plasma display and an organic EL.
The support member 4 can also support the upper end portion of the liquid crystal panel 2. For example, a support member may be installed at the position of the upper end portion of the liquid crystal panel 2 facing each support member 4 in FIG. In such a case, a hole portion into which the shaft portion of the support member can be inserted may be provided in the protruding portion 3d on the panel holder 3. Thereby, when the liquid crystal panel 2 is deformed, the support member can be rotated more accurately at a position where the variation of the liquid crystal panel 2 is small, and the stress on the liquid crystal panel 2 can be further reduced.
