CONSTITUTION:The terminal electrodes 381-38p and 391-39q are formed on the level difference parts 38a, 38b of the upper and lower sides of the liquid crystal display plate 38. The liquid crystal is connected with respective terminal electrodes 381-38p and 391-39q on the center part 38c of the liquid crystal display plate 38, and when an electrical signal is applied, a prescribed character or the like is displayed. On the other hand, electrodes are formed on the transparent electrode plate 41 from the upper side 41a to the lower side 41b.

Therefore, as shown by arrow A, the user saw the reflected light from the liquid crystal display section 3 and was aware of the display contents displayed on the liquid crystal display section 3.

However, with this configuration, the displayed content is viewed using reflected light, so in strong light such as sunlight, it is difficult to detect differences in the brightness of the reflected light, making it difficult to identify the displayed content. There were drawbacks such as similar problems occurring.

For this reason, the printed wiring board is connected to, for example, the lower side 15b of the upper and lower sides 15a and 15b of the liquid crystal display board 15;
For example, through both sides of the housing 1
It was necessary to connect it to the electrical circuit located in the lower part of 1. Therefore, the housing 11 is designed to have a relatively large margin on both sides 17 and 18 of the liquid crystal display board 15, and the width of the entire liquid crystal display 5tiff (width of the housing) w2 is made considerably larger than the width W1 of the liquid crystal display board 15.

DESCRIPTION OF THE EMBODIMENTS The above-mentioned objects of the present invention and the features of the first and second inventions will become clear from the following description of the embodiments with reference to the drawings.

FIGS. 3 and 4 are external perspective views showing one embodiment of the present invention. In particular, FIG. 3 is a perspective view of the liquid crystal display section W120 in use, and FIG. 4 is a perspective view of the liquid crystal display section W120.
2o is a perspective view of the folded state when not in use. Furthermore, FIGS. 5 and 6 show the open and closed states of the used state in which the liquid crystal display device @20 is opened as shown in FIG. FIG. 2 is a right side view of the liquid crystal display device 20 drawn to explain the state of change. First, the folding mechanism of this embodiment will be described with reference to FIGS. 3 to 6.

The liquid crystal display device 20 includes a main housing 21 , a mirror housing 22 , and a subhousing 23 .

A left arm 24 and a right arm 25 are fixed to the left and right sides of the main housing 21, respectively. left arm 24
The right arm 25 extends outward beyond the main housing 21, as shown in FIG. That is,
Both the left and right arms 24.25 have respective tip portions 24a and 25a.
Approximately half of its length on the side extends toward the opposite surface 211 of the main housing 21 . A mirror housing 22 and a sub-housing 23 are located in a corner-shaped portion surrounded by the opposite surface 211 of the main housing 21 and the left arm 24 and right arm 25 extending to the other side of the main housing 21. They are arranged in an overlapping manner (Fig. 4). At this time, main housing 2
The thicknesses of mirror housing 22 and subhousing 23 which are stacked on top of each other are made to match.

In FIG. 3, the front side of the mirror housing 22 (the side facing the opposite side 211 of the main housing 21) is
It is rotatably attached around the left and right arms 24 and 25. On the other hand, the opposite side of the mirror housing 22 and the lower side of the sub-housing 23 (the lower side of the sub-housing 23 in FIG. 3) are
It can be rotated freely in 2G.

An engaging protrusion 27 is provided approximately at the center of both left and right side surfaces of the sub-housing 23 . In addition, the left and right arms 24.
Longitudinal grooves 2β are formed in the opposing grooves (inner surfaces) of the arms 25 in the 8 direction of the length of the arm. This longitudinal groove 28 and engaging protrusions 27 formed on both left and right sides of the nub housing 23 are engaged so as to be movable along the longitudinal groove 28.

Therefore, the liquid crystal display device 20 can freely change between the state shown in FIG. 3 and the state shown in FIG. 4.

Next, description will be given mainly with reference to FIGS. 5 and 6. When opening the sub-housing 23 as shown by arrow C,
That is, when the liquid crystal display device 20 is brought into use as shown in FIG. 3, the engagement protrusion 27 moves to the right (rightward in FIG. 5) within the longitudinal groove 28 as the sub-housing 23 is opened. When the sub-housing 23 is completely opened, as shown by the dashed line in FIG.
The engagement protrusion 27 is located at the tip 281 of the longitudinal groove 28.

A small protrusion 282 is formed just before the tip of the longitudinal groove 28 . Furthermore, approximately centering on this small protrusion 282,
A small cut 283 is formed parallel to the longitudinal groove 28. Therefore, the portion including the small protrusion 282 has elasticity. Now, in FIG. 5, when the engaging protrusion 27 moves rightward within the longitudinal groove 28, it first hits the small protrusion 282.

When a force is applied to the engagement protrusion 27 and the protrusion 27 attempts to move further to the right, the small protrusion 282 is lowered by the elasticity, the engagement protrusion 27 moves to the tip 281 of the longitudinal groove 28, and the small protrusion 282 returns to its original state due to its elasticity.

The engagement protrusion 27 is stably retained at the tip 281 of the longitudinal groove 28. When the engagement protrusion 27 is in this state, the subhousing 23 is completely opened for use.

Therefore, the action of the small protrusion 282 prevents the sub-housing 23 from closing due to its own weight during use.

In addition, in FIG. 5, the circular portion at the left end of the longitudinal groove 28 is
It is used when engaging the engagement protrusion 27 with the longitudinal groove 28, and has no particular function after the engagement protrusion 27 is engaged with the longitudinal groove 28.

Next, when closing the sub-housing 23, the fourth
The case where the state shown in the figure is set will be explained. When a force is applied to the sub-housing 23 in the direction of closing (in the direction opposite to the arrow C in FIG. 5), the small protrusion 282 is bent and the engagement protrusion 27 moves leftward within the longitudinal groove 28. When the sub-housing 23 is just about to collapse, it is in the state shown in FIG.

At this time, a small protrusion 29 is formed on at least one side edge of the mirror housing 22. Then, when the sub-housing 23 is completely closed, a recess is provided on the inner surface of the arm 25 to engage with the small protrusion 29. By doing this, when the sub-housing 23 is closed, the small protrusion 29
The sub housing 23 fits into the recess (not shown), and when the liquid crystal display 20 is carried in a closed state, for example, the sub housing 23
can be prevented from opening spontaneously. Although it is preferable that the small protrusion 29 be a protrusion that can come and go, it may be a protrusion that always protrudes. For example, when the housing, arms, etc. of the liquid crystal display device 20 are molded from plastic, the plastic itself has some elasticity, so the small projections 29 will not make it difficult to open and close the sub-housing 23.

Next, a schematic configuration of this embodiment will be explained with reference to FIGS. 3 and 4.

The sub housing 23 includes a liquid crystal display panel 3 as described later.
8th grade is included. Further, a large window 231 is formed in the subhousing 23.

A milky white plate 42 is fitted into this window 231 in order to equalize the incident light. Therefore, the liquid crystal display board etc. incorporated in this sub-housing 23 are
It is possible to transmit light from the upper surface (the surface shown in FIG. 4) to the lower surface (the surface shown in FIG. 3) of 3.

Note that from the characteristics of this embodiment described later, @W of the window 231
3 can be made considerably larger than the width W4 of the sub-housing 23.

A mirror 31 is attached to the center of the upper surface (the surface visible in FIG. 3) of the mirror housing 22. With this mirror,
The light transmitted through the sub-housing 23 is reflected as indicated by the arrow in FIG. Therefore, similarly to the conventional liquid crystal display device 10 shown in FIG.

Furthermore, inside the mirror housing 22, for example, L
An electric circuit board 46 (see FIG. 11, which will be described later) made of SI is incorporated.

On the top surface of the main housing 21 are mode select switches 32, 33, and 34, and a character movement switch 3 for moving a predetermined character displayed on the liquid crystal display board.
5 and a character change switch 36 for changing the character. Each of these switches is electrically connected to the electric circuit board 46 in the mirror housing 22 described above (the connection structure is not shown), and signals from each of the switches 32 to 36 are applied to the electric circuit.

Furthermore, the electric circuit board 46 inside the mirror housing 22 is connected to a liquid crystal display board 38 built into the sub-housing 23. Then, a predetermined character or the like is displayed on the liquid crystal display board 38 by an electric signal from the electric circuit board 46.

One of the features of the present invention is an improvement in the connection structure between the liquid crystal display panel 38 built into the sub-housing 23 and the electric circuit board 46, which is an external circuit built into the mirror housing 22. Therefore, this feature will be explained in detail below.

FIG. 7 is an exploded view showing each element incorporated in the sub-housing 23. Sub housing 23
A polarizing plate 37, a liquid crystal display plate 38, a polarizing plate 39, a printing plate, a color filter, a transparent electrode plate 41, and an opalescent plate 42 are laminated and incorporated on the panel 23a on the lower surface of the One side of the liquid crystal display board 38 and the corresponding side of the transparent electrode plate 41 are electrically conductive rubber connectors 44.
electrically connected by. Further, flexible printed circuits tH43A and 43B are connected to the other side of the liquid crystal display plate 38 and the other side of the transparent electrode plate 41, respectively, for connecting the liquid crystal display plate 38 and an external circuit. At this time, it is preferable to sandwich the dummy connector 45 between the flexible printed circuits 43A and 43B and press them together.

Incidentally, the upper and lower sides of the liquid crystal display board 38 are provided with steps and are thin. This is designed to be convenient for holding a rubber connector 44 and a dummy connector 45, which will be described later.

FIG. 8 is a plan view of the liquid crystal display panel 38. Further, FIG. 9 is a plan view of the transparent electrode plate 41. With reference to FIGS. 8 and 9, connection 1M31, which is one of the features of this embodiment, will be explained.
! I will be explained in detail.

Step portions 38a on each of the upper and lower sides of the liquid crystal display board 38.

38b has terminal electrodes 381 to 38p and 3, respectively.
91 to 39q are provided at predetermined intervals of 11iA or an integral multiple thereof. Further, a liquid crystal (not shown) is provided in the central part 38c of the liquid crystal display board 38, and the liquid crystal is connected to each terminal w1 pole 381 to 38p and 391 to 39Q, and an electric signal is given to the liquid crystal from the terminal electrode. and a predetermined character etc. are displayed.

FIG. 9 is a plan view of the transparent electrode plate 41. Transparent electrode plate 4
1, from the upper side 41a to the lower side 41bk'' as shown in the figure.
tiai is provided. The six electric currents w1411 to 41n are provided at equal intervals at predetermined intervals. This transparent electrode plate 41 is placed on a liquid crystal display plate 38 shown in FIG. Therefore, for example, 381 of the terminal electrode on the upper side 388 of the liquid crystal display panel 38 and the upper side 418 of the transparent electrode plate 41
The terminal electrode 382 and the transparent electrode 412 are electrically connected, and similarly the terminal electrode 382 and the transparent electrode 412 are electrically connected, and so on.

In this way, when connecting the terminal electrodes on the upper side 38a of the liquid crystal display board 38 to an external circuit, the transparent electrode plate 41 is stacked on the liquid crystal display board 38, and the transparent electrode plate 41 gives an electrical signal to the upper side terminal electrodes. This is one of the features of this embodiment.

In this way, when connecting an external circuit to the terminal electrodes provided on the upper side 38a of the liquid crystal display board 38, for example, printed circuits are arranged on both the left and right sides of the liquid crystal display board 38, and the upper side 3Ba side terminal electrodes 381- Since it is not necessary to guide 38El to the lower side 38b side, there is no need to take up space for arranging printed wiring boards on both the left and right sides of the liquid crystal display board 38.

Since the electrodes are aligned on, for example, the lower side 38b of the liquid crystal display panel 38, connection with an external circuit is facilitated.

That is, the terminal electrodes of the liquid crystal display board 38 are terminals 1ti381 to 38p on the upper side 38a, ! The positions of the terminals 'R' poles 391 to 39q on the lower side 38b side are divided. Therefore, in general, when an external circuit is connected to these terminal electrodes, the R pole of one of the terminals must be taken out to the other terminal electrode side.

In this case, as mentioned in the background of the invention section, printed circuits are generally placed on both sides of the transparent electrode plate 38 and taken out. Therefore, it was necessary to provide a space on both sides of the liquid crystal display panel 38. In contrast, in the present invention, as described above, the terminal electrodes disposed on the upper side 38a side of the liquid crystal display board 38, for example, are connected to the lower side 38a side.
The transparent electrode plate 41 is used to take out the liquid crystal display panel 38 to the b side.Therefore, there is no need to provide a printed circuit or the like on both sides of the liquid crystal display panel 38, and space can be saved.

In addition, since the transparent electrode plate 41 is almost transparent as its name suggests, even if the transparent electrode plate 41 is stacked on the liquid crystal display plate 38, it hardly interferes with the transmission of light through the liquid crystal display plate 38. It won't be.

FIG. 10 is a perspective view of the conductive rubber connector 44 sandwiched between the liquid crystal display @38 and the transparent electrode plate 41. Also the 11th
The figure is I! in Figure 10. It is a sectional view along XI-XI.

As shown in FIG. 10, this rubber connector 44 is made of sand inch lt construction. and parts 441 on both sides
is insulating rubber, and the part 442 located in the center
is a structure in which conductive material 442a and insulating rubber 442b are alternately arranged. Therefore, the upper surface side of this rubber connector 44 is electrically connected to the lower surface side via the conductive material 442a. Further, the upper and lower surfaces of the rubber connector 44 are electrically connected to each other at the portions located on the corresponding surfaces.
In the case of non-corresponding positions, there is no conduction, so there is no short circuit between the electrodes (between the electrodes of the transparent electrode plate 41), etc.

FIG. 12 shows the lower side 38bllll#t of the liquid crystal display board 41.
FIG. 4 is a plan view of a flexible printed circuit 43A connected to an L element and a transparent electrode plate 41; Generally, the conductive portion 432 of the printed circuit 43A except for both terminals 431 is overcoated to prevent short circuits due to contact with the outside. The reason why such a flexible printed circuit 43A is used is that, as described above, this embodiment is foldable, so that the electrical wiring will not be cut when folded.

FIG. 13 shows a state in which the liquid crystal display panel 38 and the transparent electrode plate 41 are connected to an external electric circuit board 46 using the flexible printed circuit 43.

In this embodiment, since the liquid crystal display device 2o is a foldable liquid crystal display device 20, the flexible printed circuit 43 is used as described above. It is also clear from the claims that this is not a necessary requirement.

Furthermore, instead of the above-mentioned embodiment, for example, the transparent electrode plate 4
1 with a flexible transparent printed circuit has the advantage that it can be directly connected to an external circuit through the printed circuit.

Furthermore, in the above embodiment, the terminal electrodes of the liquid crystal display board 83 are transparent! ! ! Although the electrodes of the electrode plate 41 are connected by pressure contact by sandwiching the conductive rubber connector 44, the present invention is not limited to this, and other electrical connection methods may be used.

Effects of the Invention As described above, the present invention provides a liquid crystal display device in which an external circuit is connected to a liquid crystal display surface that is used in a state where light can pass through. Since a transparent N-electrode plate is used to overlap the LCD panel and connect to the terminal electrode placed on one side of the LCD panel, extra space is required to place printed circuits, etc. around the LCD panel. There is no need for this, and although the size is the smallest for a liquid crystal display, the liquid crystal display surface can be made to have the largest size, making it possible to provide a liquid crystal display device with good visibility.
