Description

[Detailed Description of the Invention] [Industrial Application Field] This invention relates to a liquid crystal display device for displaying information, and more specifically to a storage structure for storing a liquid crystal display element in a storage container.

[Prior Art] FIG. 5 is a schematic partially cutaway perspective view showing an example of a conventional liquid crystal display device. In the figure, 1
2 is a liquid crystal display element for displaying information; 2 is a container for storing the liquid crystal display element 1; a display window 3 for exposing the display surface of the liquid crystal display element 1 is formed in the container 2; A substantially L-shaped edge frame portion 4 is formed at the periphery of the display window 3.

When the liquid crystal display element 1 is stored in the storage container 2,
A gap is generated between these two 1 and 2 due to dimensional errors or deformation, so in order to prevent this, the liquid crystal display element 1 and the container 2 are fixed with an adhesive. When the liquid crystal display element 1 is fixed to the container 2 with an adhesive in this manner, the adhesive adheres to the display surface of the liquid crystal display element 1, resulting in a disadvantage that a clear display cannot be obtained.

Furthermore, conventionally, the peripheral edge 1a on the display surface side of the liquid crystal display element 1 whose back surface is held and the edge frame 4 of the container 2
A wedge member (not shown) is inserted intermittently between the liquid crystal display element 1 and the storage container 2 to absorb dimensional errors and deformation caused by dimensional errors and deformation. Are known. (Jitsukai 54-
(Refer to No. 33151) [Problems to be solved by the invention] However, when the wedge member is inserted between the liquid crystal display element 1 and the edge frame 4 of the storage container 2 as described above, when assembling the wedge member, both the above-mentioned 1 , the liquid crystal display element 1 between each of the wedge members.
A gap is generated between the container 2 and the storage container 2, allowing dust to enter. Therefore, it is necessary to inject adhesive or the like into this gap, and as in the case described above, the adhesive adheres to the display surface of the liquid crystal display element 1, resulting in a disadvantage that a clear liquid crystal display cannot be obtained.

This invention was made to improve the above-mentioned drawbacks, and the object is to provide a liquid crystal display device that is easy to assemble and provides a clear liquid crystal display.

[Means for Solving the Problems] The liquid crystal display device according to this invention includes a plurality of protrusions formed on the inner surface of the container along the insertion direction of the liquid crystal display element, and the liquid crystal display on each of these protrusions. A storage that is formed on the inner surface of the storage container in the vicinity of the display window of the storage container so as to correspond to the front end in the insertion direction of the display element, and that stores shavings of the protrusions that are generated when the liquid crystal display element is inserted. It is characterized by comprising a recessed part.

[Function] When the liquid crystal display element is in the stored state, the end face of the liquid crystal display element is pressed against the protrusion, and the protrusion presses the end face of the liquid crystal display element in a plastically deformed state, so there is no dimensional error or error between the two. Even if it is deformed, the liquid crystal display element can be fixed in the container without wobbling.

In addition, during the process of inserting the liquid crystal display element into the storage container, the end surface of the liquid crystal display element slides in pressure contact with the projections, and the shavings from the projections are formed on the inner surface of the storage container. Since it is housed in the recessed portion, there is no risk of it adhering to the inner surface of the edge frame at the peripheral edge of the display window. Therefore, the outer peripheral surface of the liquid crystal display element in its stored state is
It can be brought into close contact with the inner surface of the edge frame portion at the peripheral edge of the display window over the entire circumference.

Therefore, the liquid crystal display element can be fixed to the housing with a single touch operation without the need to fix the liquid crystal display element and the housing with adhesive as in the past, and the assembly work is easy. Since there is no risk of impurities such as adhesives adhering to the display surface of the liquid crystal display element, a clear liquid crystal display can be obtained.

[Embodiments of the invention] Examples of the invention will be described below with reference to the drawings.

FIG. 1 is a schematic perspective view showing an example of a liquid crystal display device according to this invention. In the figure, the same parts as in FIG. 5 are given the same reference numerals, and detailed explanation thereof will be omitted.

In FIG. 1, the container 2 is made of, for example, a thermoplastic material or an elastically deformable material, and on the inner surface 2a of the container 2, a plurality of protrusions 5 having a substantially triangular cross section are provided with a liquid crystal display. It is formed along the insertion direction of the element 1 (arrow a direction).

Corresponding to the front end portion 5c of the protrusion 5 in the insertion direction a of the liquid crystal display element 1, the inner surface 2a of the container 2 is provided, for example, inside the edge frame portion 4 at the peripheral edge of the display window 3. A recess 6 is formed in the side surface 4a. As clearly shown in FIG. 2, the projection 5 has a direction a in which the liquid crystal display element 1 is inserted.
A tapered surface 5a is formed at the rear end 5b of the holder.

Now, the liquid crystal display element 1 is inserted into the container 2 in the direction of arrow a from the state shown in FIG.

In the stored state of the liquid crystal display element 1 shown in FIG. 3, the end face 1b of the liquid crystal display element 1 is pressed against the protrusion 5, and the protrusion 5 presses the end face 1b of the liquid crystal display element 1 in a plastically deformed state. From, both 1, 2
Even if there is a dimensional error or deformation, the liquid crystal display element 1 can be fixed in the container 2 without wobbling.

In addition, during the process of inserting the liquid crystal display element 1 into the storage container 2 in the direction of arrow a from the state shown in FIG. Since the shavings 7 of the protruding ridges 5 are stored in the recess 6 formed on the inner surface 2a of the storage container 2, there is no risk of them adhering to the inner surface 4a of the edge frame portion 4 at the peripheral edge of the display window 3. do not have. Therefore, the outer peripheral surface 1 of the liquid crystal display element 1
c is the inner surface 4a of the edge frame portion 4 at the periphery of the display window 3 in the stored state, as shown in FIG.
It can be closely attached to the entire circumference.

Therefore, as in the conventional case, the liquid crystal display element 1
The liquid crystal display element 1 can be fixed to the storage container 2 with a single touch operation without using adhesive to fix the liquid crystal display element 1 to the storage container 2, making the assembly process easy, and impurities such as adhesive can be removed from the liquid crystal display. Since there is no risk of adhesion to the display surface of the element 1, a clear liquid crystal display can be obtained.

Note that when inserting the liquid crystal display element 1 into the container 2 in the direction of arrow a from the state shown in FIG.
Since the end surface 1b of the liquid crystal display element 1 is guided into the storage container 2 along the tapered surface 5a formed at the rear end 5b of the projection 5 in the insertion direction a, the storage operation is easy. However, it goes without saying that this tapered surface 5a may be provided as necessary.

Further, in the above embodiment, the storage recess 6 for storing the shavings 7 has a structure in which the shavings 7 are stored in a space closed by the liquid crystal display element 1 as shown in FIG. As shown in FIG. 4, the storage recess 6 may have a discharge port 9 communicating with the outside, so that the shavings 7 of the protrusion 5 can be discharged to the outside. By adopting such a configuration for discharging the shavings 7, it is possible to more effectively prevent the shavings 7 of the protrusion 5 from adhering to the inner surface 4a of the edge frame portion 4 at the peripheral edge of the display window 3. I can do it.

[Effects of the invention] As described above, according to the liquid crystal display device of this invention, the liquid crystal display element can be stored with a single touch operation without fixing the liquid crystal display element and the storage container with adhesive as in the conventional case. It can be fixed to the device, the assembly work is easy, and there is no risk of impurities adhering to the display surface of the liquid crystal display element unlike when fixing with adhesive, so a clear liquid crystal display can be obtained.
