Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid crystal display device suitable for use in a display system with a large display screen.

Today's liquid crystal display devices display characters such as those used in portable clocks and calculators.
While manufacturing for numerical display is becoming more and more compact, the increasing number of patterns has led to larger display screens.
Thinner products are becoming required in a wide range of fields.

However, when driving a liquid crystal display device, it is difficult to use an unnecessarily large number of time divisions due to the following characteristics: technical difficulty in keeping the force uniform across the screen)
However, there were certain limits to how large the screen could be. In other words, it is technically difficult to obtain the mechanical strength necessary to keep the gap between the glass substrates constant while keeping the thickness of the liquid crystal display device small.

The present invention has been made in view of the conventional drawbacks of force, and the strength of the glass substrate is increased between the transparent electrode patterns. The purpose of the present invention is to provide a liquid crystal display device that can be held uniformly and that can have a large screen.

In order to achieve this objective, a plurality of transparent electrode patterns are formed vertically on one of two opposing glass substrates and horizontally on the other, and these are overlapped to seal the periphery. In a liquid crystal display device in which a liquid crystal is sealed with a material to form a cell and a liquid crystal is housed in the cell, an insulating spacer is printed and printed between the plurality of adjacent transparent electrode patterns. It was due to the structure.

Examples of the present invention are described below in detail with reference to the drawings.

FIG. 1 specifically shows one embodiment. In the figure, 1.2 is a glass substrate, and on the lower surface of the glass substrate 1 and the upper surface of the glass substrate 2, a plurality of band-shaped transparent molds and polar patterns 3 and 4 are provided by a vapor deposition method or the like.
The electrode patterns 3 and 4 of these electrodes are arranged so as to intersect with each other! are doing.

``Also, a spacer and a sealing material (not shown) are interposed between the glass substrates 1 and 2 on which the electrode patterns 3 and 4 are provided. A liquid crystal N5 is provided in the gap γ surrounded by the material to form a cell fL.A dye can also be mixed into this liquid crystal layer 5.

Furthermore, a liquid crystal alignment control film is provided on each of the electrode patterns 3 and 4.

A polarizing plate 7.8 is provided on the upper surface of the glass substrate 1, and a reflecting plate 8 is provided on the lower surface of the polarizing plate 7.

Note that the electrode pattern 3.4 can also be obtained by uniformly coating the glass substrates 1 and 2 with a transparent conductive film, and then selectively etching it using a resist method.
Ru. Further, the liquid crystal is injected into the above-mentioned gap through an opening provided in a part of the sealing material and then sealed.

In addition, spacers 9 and 10 made of a material with good insulation properties and high strength and rigidity are printed 1 between adjacent electrode patterns 3 and 7 of each of the electrode patterns 3 and 4. Adjacent electrode patterns 3.4 are q++ coupled to each other by the dots, and each electrode pattern is given rigidity against bending or bending in the longitudinal direction. Therefore, the bending strength of the glass substrates 1 and 2 as well as of the entire cell is significantly improved. Further, since each spacer 9.10 is inserted between the electrode patterns 3.4 by printing, there is no need to increase the thickness of the entire cell.

As explained in detail above, according to the present invention, a plurality of transparent electrode patterns are formed on one of the two opposing glass substrates in the vertical direction (r) and in the horizontal direction on the other. The periphery of each cell is sealed with a sealing material so as to provide a predetermined gap between the cells, and in a liquid crystal display device in which a liquid crystal is housed in this cell, By printing an insulating spacer in a raised manner between the plurality of transparent electrodes that fit together, the bending strength in the longitudinal direction of the electrode pattern of the glass substrate is increased between each electrode pattern.
In addition, the strength of the entire cell and the entire liquid crystal display device is improved. As a result, the gap between the glass substrates can be kept uniform over the entire screen, and a large-screen liquid crystal display device with stable characteristics can be obtained.
