Abstract

PROBLEM TO BE SOLVED: To provide a shield plate improving yield and productivity in a liquid crystal display device. SOLUTION: This shield plate is provided with an opening part 2 for sliding/ inserting a liquid crystal panel PN from the side on the side surface, and the inner size w1 in the direction perpendicular to this slide direction is made nearly equal to the size (w) of the panel PN in this direction, and pawls 3a, 3b engaged with the inserted panel PN are provided. When the panel is mounted, the panel PN is inserted into the shield plate 1 by sliding it from the side through the opening part 2. Then, since the inner size w1 of the shield plate 1 is nearly equal to the size (w) of the panel PN, the liquid crystal panel PN is held into the shield plate 1, and the pawl parts 3a, 3b are engaged with the liquid crystal panel PN. Thus, the liquid crystal panel PN is fixed sufficiently to the shield plate 1.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a shield plate (bezel) as an outer frame for holding and protecting a panel of a liquid crystal display device, and more particularly to an improvement in yield and productivity of the liquid crystal display device. About.

[0002]

2. Description of the Related Art In a liquid crystal panel manufacturing process, in a module manufacturing process following a panel manufacturing process, an integrated circuit for driving a liquid crystal is mounted, a flexible printed cable for connecting to a computer or the like is added, and a liquid crystal display is mounted. The panel is mounted on the shield plate.

[0003] The shield plate has a function as an outer frame for holding and protecting the liquid crystal panel, and the liquid crystal panel mounted on the shield plate is used, for example, in a portable V camera.
Attached to the viewfinder of TR.

FIG. 3 shows an example of the structure of a conventional shield plate. The shield plate 11 has an L-shaped cross section in order to insert the liquid crystal panel PN from above, and the inner dimension w11 between both side surfaces in the width direction (horizontal direction in the drawing) is the dimension of the liquid crystal panel PN. It is slightly larger than w. Also,
In order to allow the flexible printed cable FPC added to the liquid crystal panel PN to pass through, the side surface is partially cut away.

FIG. 4 shows an example of a work of mounting a liquid crystal panel on the shield plate. After inserting the liquid crystal panel PN,
In the space between the shield plate 11 and the liquid crystal panel PN,
The liquid crystal panel P is filled by filling a silicon-based room temperature curing resin 13 using a dispenser (resin coating device) 12.
N was fixed to the shield plate 11. (TFT, CF
Are a TFT substrate and a color filter substrate which are components of the liquid crystal panel PN, respectively. )

[0006]

However, such a conventional mounting operation of a liquid crystal panel has the following problems. (1) Since the space between the shield plate 11 and the liquid crystal panel PN is narrow, when the space is filled with the silicon-based room-temperature-curable resin 13, the amount of filling may be excessive or insufficient, or the shield plate near the space may be used. 11 and liquid crystal panel PN
In some cases, the silicon-based room-temperature-curable resin 13 may adhere to the surface of the liquid crystal display device, which causes instability of the quality of the liquid crystal display device and deterioration of the yield.

(2) Filled silicone-based room temperature cured resin 1
When the liquid crystal panel PN is cured, the liquid crystal panel PN becomes a shield plate 1.
Since it takes 24 hours or more before it is sufficiently fixed to 1, the productivity of the liquid crystal display device is considerably reduced.

The present invention has been made in view of the above points, and has as its object to provide a shield plate capable of improving the yield and productivity of a liquid crystal display device.

[0009]

In the shield plate according to the present invention, an opening is provided on a side surface for inserting a liquid crystal panel by sliding the liquid crystal panel from the side, and an opening in a direction perpendicular to the sliding direction is provided. It is characterized in that the size is substantially equal to the size of the liquid crystal panel in this direction, and that a claw that engages with the inserted liquid crystal panel is provided.

When a liquid crystal panel is mounted on this shield plate, the liquid crystal panel is inserted into the shield plate by sliding the liquid crystal panel from the side through an opening on the side surface of the shield plate. Then, since the inner dimension of the shield plate in the direction perpendicular to the sliding direction is substantially equal to the size of the liquid crystal panel in this direction, the liquid crystal panel is sandwiched in the shield plate and the claws are engaged with the liquid crystal panel. Thereby, the liquid crystal panel is sufficiently fixed to the shield plate.

Thus, the liquid crystal panel is fixed to the shield plate by a simple operation. In addition, since the silicon-based room-temperature-curable resin is not used when mounting the liquid crystal panel on the shield plate, deterioration in yield and reduction in productivity due to the use of the silicon-based room-temperature-curable resin are eliminated, and manufacturing costs are reduced. I do.

Embodiments of the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 shows an example of the structure of a shield plate according to the present invention. The shield plate 1 has an opening 2 for slidingly inserting the liquid crystal panel PN from the side and provided on the entire surface of one side surface, and the claw portions 3a and 3b (claws) which engage with the inserted liquid crystal panel PN. Are provided on both sides of the opening 2.

An inner dimension w1 between both side surfaces of the shield plate 1 in the width direction (a direction orthogonal to the sliding direction) is substantially equal to a dimension w of the liquid crystal panel PN in this direction. Also, the depth of the shield plate 1 (the distance in the sliding direction from the tips of the claws of the claws 3a and 3b to the side surface facing the opening 2) is substantially equal to the size of the liquid crystal panel PN in the sliding direction. Has become.

FIG. 2 shows an example of the operation of mounting the liquid crystal panel on the shield plate. As shown in FIG.
N is inserted into the shield plate 1 by sliding from the side through the opening 2. Then, as shown in FIG. B, the inner dimension w1 in the width direction of the shield plate 1 is substantially equal to the dimension w of the liquid crystal panel PN, so that the liquid crystal panel PN is sandwiched in the shield plate 1 in the width direction and the claw portion is formed. Since 3a and 3b engage with the liquid crystal panel PN, the liquid crystal panel PN is sandwiched in the shield plate 1 even in the sliding direction. As a result, the liquid crystal panel PN is sufficiently fixed to the shield plate 1. After the liquid crystal panel PN is inserted into the shield plate 1 as described above, the opening 2 also serves to pass the flexible printed cable FPC.

In the above embodiment, the claws 3a and 3b are provided on both sides of the opening 2. However, similar claws may be provided on the lower and upper portions of the opening 2, for example. .
In addition, the present invention is not limited to the above-described embodiments, and may take various other configurations without departing from the gist of the present invention.

[0016]

As described above, according to the shield plate of the present invention, the following effects can be obtained. (1) When mounting the liquid crystal panel on the shield plate, the liquid crystal panel can be fixed to the shield plate by a simple operation. (2) Deterioration of yield and decrease in productivity due to the use of a silicon-based room temperature curable resin can be eliminated, and the quality of the liquid crystal display device can be stabilized, the yield can be improved, and the productivity can be improved. (3) The manufacturing cost of the liquid crystal display device can be reduced.
