Description

[Detailed description of the invention] [Industrial application field] The present invention uses a liquid crystal display element, in which liquid crystal is sealed between two transparent substrates stacked on each other, as a cover case for electric equipment such as a word processor. The present invention relates to a liquid crystal display device mounted on a liquid crystal display device.

[Conventional technology]

Conventionally, when forming a polarizing layer on each of the surfaces of two transparent substrates that are superimposed on each other, this type of liquid crystal display device has a structure in which both transparent substrates 2 and 2 of the liquid crystal display device 1 are arranged as shown in FIG. The configuration is such that polarizing films 4 and 5 made of a synthetic resin such as polyvinyl alcohol are attached to each of the surfaces 3.

Conventionally, when the liquid crystal display element 1 is mounted on a cover case 6 of an electric device such as a word processor, for example, Japanese Unexamined Patent Publication No. Sho 62-172322 and Japanese Unexamined Utility Model Publication No. Sho 57-32978 disclose. In addition, as shown in FIG. 3, the liquid crystal display element 1 is
On the inner surface side, one of the transparent substrates 2 of the liquid crystal display element 1 is mounted so as to be seen in a display window 7 formed in the cover case 6, while the other of the one transparent substrate 2 is provided in the display window 7 of the cover case 6. Protective transparent plate 8 for preventing the polarizing film 4 on the surface of the transparent substrate 2 from being damaged.
Is fitted so that the surface 8a of the protective transparent plate 8 is substantially flush with the surface 6a of the cover case 6.

[Problems to be solved by the invention]

However, attaching the protective transparent plate 8 to the display window 7 in the cover case 6 in this manner not only increases the number of parts, but also requires time and effort for attaching the protective transparent plate 8. As a result, the cost is greatly increased, and as described above, the weight is increased because the protective transparent plate 8 is required,
There is a problem that the thickness dimension increases.

An object of the present invention is to provide a liquid crystal display device that solves these problems.

[Means for solving the problem]

In order to achieve this technical problem, the present invention provides a liquid crystal display element comprising two transparent substrates stacked on top of each other and injecting liquid crystal between them, on the inner surface side of a cover case in an electric device such as a word processor. In a liquid crystal display device, one of the transparent substrates of the element is mounted so as to be seen in a display window of a cover case, and a polarizing film is attached to a surface of the one transparent substrate of the liquid crystal display element. Affixed only to the portion of the surface of one of the transparent substrates in the liquid crystal display element within the display window in the cover case, and while making this polarizing film hard, the thickness of this polarizing film is The thickness is such that the surface of the polarizing film is substantially flush with the surface of the cover case. "

[Actions and effects of the invention]

Thus, the polarizing film in the liquid crystal display element is
The liquid crystal display device is configured such that it is adhered only to the portion inside the display window of the cover case on the surface of one of the transparent substrates, and the polarizing film is made of a hard material, and the thickness of the polarizing film is reduced on the surface. By making the thickness substantially the same as the surface of the cover case, it is possible to prevent the polarizing film on the surface of the one transparent substrate from being damaged, and to prevent the surface of the polarizing film from being damaged. And the surface of the cover case can be made substantially coplanar so that there is no step between them,
It is possible to omit fitting the protective transparent plate into the display window in the cover case as in the conventional case.

Therefore, according to the present invention, the number of parts and the number of assembling steps are reduced, so that the cost can be greatly reduced. Further, the thickness can be reduced, and the size of the liquid crystal display device can be reduced. This has the effect of being able to achieve a reduction in weight.

〔Example〕

Hereinafter, an embodiment of the present invention will be described with reference to the drawings (FIGS. 1 and 2).
Will be described.

In the figure, reference numeral 10 denotes a liquid crystal display element in which two transparent substrates 11 and 12 are overlapped with each other and a liquid crystal is sealed therebetween, and this liquid crystal display element 10 is a cover case 13 of an electric device such as a word processor. Inside, one transparent substrate 12 of the liquid crystal display element 10 is covered with a cover case 13.
It is mounted so that it can be seen inside the display window 14 formed in the camera.

Further, both transparent substrates 11, 12 in the liquid crystal display device 10
Polarizing films 15 and 16 are adhered to the respective surfaces of.

In this case, the polarizing film 15 for the upper surface of one of the transparent plates 11 and 12 is adhered only to the portion of the upper surface of the one transparent substrate 11 within the display window 14 in the cover case 13. And, the polarizing film 15 is made of a hard synthetic resin,
The thickness dimension is made equal to the step dimension from the surface of the cover case 13 to the surface of the one transparent substrate 11.

The surface 15a of the polarizing film 15 has been subjected to a non-glare treatment.

With this configuration, the liquid crystal display element 10
The polarizing film 15 adhered to the surface of the one transparent substrate 11 can be prevented from being scratched, and the surface 15a of the polarizing film 15 and the surface 13a of the cover case 13 cannot have a step therebetween. Thus, it is possible to omit the fitting of the protective transparent plate into the display window 14 in the cover case 13 as in the related art, as described above.
