BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat panel type display device such as a liquid crystal display device, and more particularly to a support structure for a flat type display panel.

[0002]

2. Description of the Related Art In recent years, as devices have become smaller, lighter, and thinner, flat panel electronic display devices (hereinafter referred to as flat panel display devices) represented by liquid crystal display devices used in various equipment have become thinner. Is being done,
The support structure of the flat display panel is also devised to be thinner.

As a conventional example, a liquid crystal display device having a backlight will be described below as an example of a flat panel type display device.

As shown in FIG. 8, a conventional liquid crystal display device 1
Has a rectangular liquid crystal panel 2 and a rectangular light guide plate 3 for a backlight provided on the lower surface side of the liquid crystal panel 2. The liquid crystal panel 2 is composed of panel materials 4 and 5 made of a pair of glass plates bonded to each other, and polarizing plates 6 provided on the front and back of these panel materials 4 and 5. The lower panel material 4 is a TFT panel to which a shutter function for controlling light from the light guide plate 3 is added. The upper panel material 5 is a color filter (CF) panel provided with dots of three primary colors for color display.

The liquid crystal panel 2 and the light guide plate 3 are held at their peripheries by being sandwiched between a synthetic resin holding frame 11 formed in a rectangular frame shape and outer frames 16 and 17.

A holding wall 15 is formed on the upper side of the holding frame 11 and extends in the circumferential direction.
The liquid crystal panel 2 is disposed on the inner peripheral side of the and is positioned and held in a state of being juxtaposed along the surface direction by the holding surface 15a which is the inner surface thereof.

A holding recess 12 is formed on the lower side of the holding frame 11, and the light guide plate 3 is fitted and held in the holding recess 12. Further, the holding frame 11 is provided with a spacer portion 13 which is interposed between the light guide plate 3 and the liquid crystal panel 2 in the circumferential direction, and the spacer portion 13 is provided above the light guide plate 3 to extend above the light guide plate 3. On the side,
The liquid crystal panel 2 is provided with the panel material 4 below the spacer section 1
It is arranged in a state of being in contact with 3.

As described above, the liquid crystal panel 2 and the light guide plate 3
Outer frames 16 and 17 such as upper and lower holding metal fittings made of a frame body having an L-shaped cross section are fitted into and below the holding frame 11 that holds the periphery of the outer frames 16 and 17, respectively.
The light guide plate 3 and the liquid crystal panel 2 are integrated with the holding frame 11 by mating and coupling the two components to form a liquid crystal display module.

And such a liquid crystal display module is
It is designed to be attached to the display housing of information processing equipment.

As shown in FIGS. 9A and 9B, the liquid crystal panel 2 has two sides of the CF substrate 5 so that electrode terminals (not shown) provided along two adjacent sides of the TFT substrate 4 are exposed. It is arranged so as to be arranged at a position retracted from the end face of the TFT substrate 4. Then, as shown in FIG. 9C, the printed circuit board 23 on which the control semiconductor IC is mounted and the electrode terminals of the TFT substrate 4 are electrically connected via the TCP (tape carrier package) 24.

In order to produce such a liquid crystal display panel 2, first, as shown in FIG. 10A, a panel material 4 which is a TFT panel is predetermined from a panel material 4 side which is a panel 2a obtained by laminating panel materials 4 and 5 having the same outer shape. Outline (dotted line 4 in FIG. 10A)
1B), a cutting groove 201 is formed by the high-penetration cutter 21 as shown in FIG. 10B, and then the panel 2a is inverted and a predetermined impact is applied by a hammer from the opposite side of the cutting groove 201. In addition, only the panel material 4 which is a TFT panel is broken.

Next, as shown in FIG. 10C, a high permeation cutter 21 similarly cuts along a predetermined outer shape (outer shape indicated by a chain double-dashed line 51 in FIG. 10C) from the panel material 5 side which is a CF panel. After making a groove, the panel 2a is inverted and a predetermined impact is applied by a hammer from the opposite side of the cutting groove to break only the CF panel.

In this way, as shown in FIG. 9A,
The liquid crystal panel 2 including the panel materials 4 and 5 having a predetermined outer shape is obtained.

The liquid crystal panel 2 whose outer periphery is cut as described above
As shown in FIG. 9B, the chamfering process is performed by polishing the front and back corners of the cut surface. In addition,
This chamfering process is also performed on the corners of the panel material 4 on the bonding surface side of the panel material 4 on each side in the longitudinal direction and the width direction having the electrode to which the TCP is connected.

In the liquid crystal panel 2 which has been chamfered as described above, the printed circuit board 23 is connected via TCP 24 to each side in the longitudinal direction and the width direction having the electrodes, as shown in FIG. 9C. Then, it was stored in the holding wall 15 of the holding frame 11.

[0016]

By the way, when the liquid crystal panel 2 is manufactured by cutting the panel 2a so as to have a predetermined outer shape as described above, the TCP 24 is not connected to each other in the longitudinal direction and the width direction. On one side, the panel members 4 and 5 are cut with the same outer shape so that the cut surfaces thereof coincide with each other, but at the boundary between the panel members 4 and 5, as shown in FIG. Of a sharp edge 501
Was sometimes exposed.

The edge 501 cannot be chamfered because the edge 501 is slightly displaced, and therefore, the edge 501 must be stored and held in the holding wall 15 of the holding frame 11 as it is.

As shown in FIGS. 12A and 12B, the liquid crystal panel 2 in which the panel materials 4 and 5 are displaced from each other in this way is supported by the holding frame 11 together with the light guide plate 3 for liquid crystal display. In the case of the device 1, the liquid crystal panel 2
Edge 401 of the panel material 4 caused by the displacement of the panel materials 4 and 5 during or after the mounting on the holding frame 11.
Alternatively, the edge 501 of the panel material 5 may scrape the holding surface 15a of the holding wall 15 of the holding frame 11.

The holding surface 1 of the holding wall 15 is thus formed.
When 5a is scraped off, the foreign matter scraped off from the holding wall 15
The light guide plate 3 is inserted between the liquid crystal panel 2 and the light guide plate 3.
However, there is a problem that the light emitted from the liquid crystal display device is partially blocked to cause a problem in the display by the liquid crystal display device 1. This problem also occurs in a reflective liquid crystal display device that uses a reflective plate instead of the light guide plate.

Further, since the holding frame 11 is provided over the thickness direction so as to surround the periphery of the liquid crystal panel 2 by the holding wall 15, the removal work of the liquid crystal panel 2 for inspection, maintenance or replacement. However, there is a problem in that it is difficult to mount the liquid crystal panel 2 on the holding frame 11 as well.

Needless to say, these problems are not limited to the liquid crystal display panel but also occur in other flat panel type display devices such as a plasma display device in which two glass substrates are arranged so as to face each other.

Therefore, an object of the present invention is to provide a flat panel type display device having a holding frame structure capable of suppressing the holding frame from being scraped by the edge of a flat display panel such as a liquid crystal display panel. is there.

Another object of the present invention is to provide a flat panel type display device having a holding frame structure capable of suppressing the occurrence of display defects due to foreign matter.

Still another object of the present invention is to provide a flat panel type display device having a holding frame structure capable of easily mounting and removing the display panel.

That is, only the end surface of the TFT substrate 4 contacts the holding frame 11, and the end surface of the CF substrate 5 does not contact the holding frame 11. Thereby, the holding wall 1
The holding surface 15a of No. 5 has the upper end position, that is, the edge portion 31.
a is located below the boundary position between the panel materials 4 and 5. In the case of a liquid crystal display panel,
Since the liquid crystal layer is interposed between the substrates, the boundary between the pair of substrates has a certain width corresponding to the thickness of the liquid crystal layer, but the boundary at that time is based on the plane parallel to the inner surface of the back side substrate. Becomes

In other words, the height dimension of the holding surface 15a is smaller than the thickness dimension of the substrate 4 contacting it. That is, the holding frame 11 is provided with the holding wall 15 and the peripheral support portion 13 which are the end surface support portions that come into contact with the end surface and the peripheral surface of the back surface side substrate 4 of the display panel, respectively. Further, the distance between the end surface support portion, that is, the support surface upper end portion 31a of the holding wall 15 and the support surface of the spacer portion 13, which is the peripheral support portion, is smaller than the thickness of the back surface side substrate 4. Therefore, the holding surface 15a can contact only the end surface of the panel material 4.

As shown in FIG. 3, the intersection point P between the taper portion 31 and the extension line extending horizontally from the boundary between the panel members 4 and 5 of the liquid crystal panel 2 to the outer peripheral side is a predetermined dimension L from the holding surface 15a. It is located horizontally away from the outer circumference.

That is, the panel material 4 below the liquid crystal panel 2
When the end face formed of the cut surface of the panel member 4 abuts the holding surface 15a of the holding wall 15, a gap of a predetermined size L is formed in the horizontal direction between the upper end of the panel material 4 and the tapered portion 31.
The taper portion 31 is inclined. In addition, this predetermined dimension L
Is about 0.5 mm here. The reason is that the maximum amount of displacement between the panel materials 4 and 5 forming the liquid crystal panel 2 is about 0.3 mm.

As shown in FIGS. 1 and 4, the holding wall 15 of the holding frame 11 is formed with a plurality of notches 32 at intervals in the circumferential direction.

Here, as shown in FIGS. 5 and 6, an edge formed by the displacement of the panel materials 4 and 5 on the end surface which is the cut surface of the liquid crystal panel 2 housed on the inner peripheral side of the holding wall 15. Even if there are 401 and 501, the upper end position of the holding surface 15a of the holding wall 15 is lower than the boundary position between the panel members 4 and 5, and it can contact only the end face of the lower panel member 4. Therefore, the edges 401 and 501
And the holding wall 15 do not interfere with each other.

In particular, as shown in FIG. 5, even if the upper panel material 5 projects toward the outer peripheral side and is displaced, the end surface of the lower panel material 4 of the liquid crystal panel 2 is held by the holding surface 15 of the holding wall 15.
When it comes into contact with a, the upper end of the panel material 4 and the taper portion 3
1, the taper portion 31 is inclined so that a gap of a predetermined dimension L of about 0.5 mm is formed in the horizontal direction, and
Since the maximum amount of displacement between the panel materials 4 and 5 forming the liquid crystal panel 2 is about 0.3 mm, the protruding edge 501 of the upper panel material 5 does not interfere with the tapered portion 31.

As described above, according to the liquid crystal display device of the present embodiment, the holding wall 15 that surrounds the liquid crystal panel 2 is provided with the panel material below the boundary between the panel materials 4 and 5, that is, below the panel material. Since the holding surface 15a that can come into contact with only the end surface of the panel material 4 is formed on the 4 side, the liquid crystal panel 2

The removal work of the panel 2 can be facilitated.

Moreover, since the notch 34 is formed at the corner of the holding wall 15, the corner of the liquid crystal panel 2 is located at the holding wall 15.
It is possible to reliably prevent the interference of the liquid crystal panel 2 with the holding wall 15. Therefore, it is possible to prevent a defect due to the corner of the liquid crystal panel 2 interfering with the holding wall 15.

In the above example, the tapered portion 31 is formed on the entire holding wall 15 of the holding frame 11, but the tapered portion 3 is formed.
1 may be formed on the holding wall 15 that holds at least the cut surface of the side other than the side having the electrodes of the liquid crystal panel 2.

Further, what is shown in FIG. 7 is a holding frame 11 in which a tapered portion 31 is formed only on the holding wall 15 which holds the other three end faces except one side in the longitudinal direction having the electrodes of the liquid crystal panel 2. is there.

In the case of the holding frame 11, the holding wall 15 in which the taper portion 31 is not formed is brought into contact with the end face of one side in the longitudinal direction having the electrodes of the liquid crystal panel 2 to position the holding wall. The liquid crystal panel 2 is housed in 15. With this storage, the end surfaces other than the end surfaces that are brought into contact with the holding wall 15 are guided into the holding wall 15 by the tapered portion 31 formed on the holding wall 15 and stored smoothly during storage.

In the case of the holding frame 11, particularly, when the taper angle of the taper portion 31 of the holding wall 15 for holding the end faces on both sides of the end face abutting the holding wall 15 is made gentle, Can be stored smoothly.

If the holding wall 15 is provided at a position for holding the corner portion of the liquid crystal panel 2, the liquid crystal panel 2 can be securely held and kept in the state of being housed in the holding frame 11. .
