Abstract

PURPOSE:To decrease the radiation noises from a display surface and to improve display quality by providing a conductive meshed electrode which is disposed via an insulating layer between at least one transparent electrode and glass substrate and exhibits a meshed pattern shape. CONSTITUTION:This display element is constituted by sandwiching a liquid crystal layer 5 from both sides by the glass substrate 1, an X electrode 4, the glass substrate 7 and a Y electrode and further by disposing the conductive meshed electrode 2 having the meshed pattern running vertically and horizontally between dots via the insulating layer 3 between the glass substrate 1 and the X electrode 4. This conductive meshed electrode 2 has a sufficient electrical conductivity and is grounded to a frame ground in order to obtain a sufficient shielding effect. The mesh is constituted of the black fine patterns which shut off the transmitted light. The high-frequency noises transmitted therethrough are thus attenuated by the grounded conductive meshed electrode 2 and the display which is sharp in the edge parts of the respective dots is obtd. by the black mesh pattern. The radiation noises from the display surface are decreased and the display quality is improved by providing the conductive meshed electrode to the display element.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a device structure of a dot matrix liquid crystal display (hereinafter referred to as LCD) display element.

[Conventional technology]

FIG. 3 is a sectional view showing an example of a conventional matrix type LCD display element.

Conventionally, this type of matrix type LCD display element has a structure in which a liquid crystal layer 33 is sandwiched between glass substrates 31 and 35 on which X electrodes 32 and Y electrodes 34 are printed, as shown in FIG.

[Problem that the invention seeks to solve]

The conventional matrix type LCD display element described above has the following drawbacks.

1. Radiation noise from the back surface drive circuit is radiated through the display surface.

2 If the space between the dots is the background color, check the continuity of the dots.

[Means for solving problems]

The IJ box type liquid crystal display element of the present invention does not sandwich a liquid crystal layer between separate transparent electrodes and glass substrates from both sides, but an insulating layer is interposed between at least one of the transparent electrodes and the glass substrate. It is equipped with conductive mesh electrodes arranged in a mesh-like pattern.

〔Example〕

Next, one embodiment of the present invention will be explained with reference to the drawings.

1 and 2 are a sectional view and a plan view of an embodiment of the present invention.

This embodiment includes glass substrates 1 and 7, a conductive mesh electrode 2,
Insulating layer 3. It has an X electrode 4, a liquid crystal layer 5, and a Y electrode 6.

The liquid crystal layer 5 is placed on the glass substrate 1 from both sides. X electrode 4 and glass substrate 7. The glass substrate 1 is sandwiched between the Y electrodes 6 and
A conductive mesh electrode 2 having a mesh pattern running vertically and horizontally between the dots is arranged between the X electrode 4 and the X electrode 4 with an insulating layer 3 interposed therebetween. This conductive mesh electrode 2 has sufficient conductivity and is grounded to the frame ground in order to obtain a sufficient shielding effect. Furthermore, the mesh is composed of a black fine pattern that blocks transmitted light.

In this embodiment with such a configuration, B shown in FIG.
High frequency noise transmitted from the surface to the A surface is attenuated by the grounded conductive mesh electrode 2.

Next, regarding the display pattern according to this embodiment, as shown in FIG.
Since the black mesh pattern of the filter 22 is arranged in a uniform manner, there is no blank space between each dot, and the edges of each dot are displayed sharply.

〔Effect of the invention〕

As described above, the present invention has the effect of reducing radiation noise from the display surface and improving display quality by providing a conductive mesh electrode between the transparent electrode and the glass substrate. ,
