Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a liquid crystal display element, and more particularly to a display figure forming structure suitable for a negative display type liquid crystal display element 4 used in a reflective type.

[Background of the invention]

As shown in FIGS. 1 and 2, a conventional negative display type liquid crystal display element has an upper glass substrate 2 on which an upper plate electrode pattern 1 is formed, and a lower glass substrate 2 on which a lower plate electrode pattern 3 is formed. The plate glass substrate 4 is sealed with a sealing material, and liquid crystal is sealed inside. Further, an upper polarizing plate 5 and a lower polarizing plate 6 are bonded to the outer sides of the upper glass substrate 2 and the lower glass substrate 4, respectively, and the outer side of the lower polarizing plate 6 (reflecting plate or semi-transmissive reflecting plate 7 are bonded together to form a reflective or semi-transmissive type.Also, the overlapping part of the upper plate electrode pattern 1 and the lower plate electrode pattern 3 is used as a display part, and in order to further improve the visibility, the area around the display part is The shielding film 8 is formed by mask printing the upper polarizing plate 51 corresponding to the above.

However, since the shielding film 8 is printed on the outer side of the display section, when used as a reflective type, as shown in FIG. (This has the disadvantage that the bright area 11 inside the display section 9 becomes very difficult to see.

[Purpose of the invention]

An object of the present invention is to provide a liquid crystal display element that provides an easy-to-see display.

[Summary of the invention]

In the present invention, a display area formed by an upper plate electrode pattern and a lower plate electrode pattern is formed wider than a predetermined display area, and a shielding film is formed by mask printing other than the predetermined display area on the lower plate polarizing plate surface or lower plate glass substrate surface. It is characterized by the formed koshu.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 4 and 5. Note that the same or equivalent members ζ as in FIGS. 1 and 2 will be described with the same reference numerals.

The display area formed by the upper plate electrode pattern 1 and the lower plate electrode pattern 3 is formed wider than a predetermined display area.

Further, the shielding film 8 is formed by mask printing on the surface of the lower polarizing plate 6 other than the predetermined display areas.

In this way, since the shielding film 8 is formed to shield the periphery of the inner periphery of the display section (lighting section) by the electrode pattern E and 3F, the bright section of the predetermined display section (inside the shield Ijk3) 11f This will reduce the influence of the shadow of the dark area around the display area due to the lighting pattern 1.3 Also, since the shielding film 8 is in close contact with the reflector or semi-transparent reflector 7, the shielding film The shadows in the dark areas of 8 become darker, and the display becomes easier to see from this point of view.

Figure 6 shows an example of the display section. Outer solid line shape 1
2 is the electrode pattern 1.3 (this is the lighting part, the inner dotted line figure 13 is the predetermined display part inside the a-screening film 8,
The area inside the dotted line is bright and the area outside is dark.

Note that even if the shielding film 8 is formed on the surface of the lower glass substrate 1, the same effect as in the above embodiment can be obtained.

〔Effect of the invention〕

According to the present invention, the display area formed by the upper plate electrode pattern and the upper plate electrode pattern is formed wider than the predetermined display area, and the areas other than the predetermined display area are mask-printed on the lower polarizing plate surface or the lower glass substrate surface to be shielded. Since it is formed by forming a film, a very easy-to-read display can be obtained.
