本発明は、液晶表示素子に係り、特に、電極部の一部に
絶縁体を間にはさんだ導体の積層部分を有する基板を用
いて構成される液晶表示素子に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a liquid crystal display element, and more particularly to a liquid crystal display element constructed using a substrate having a laminated portion of a conductor with an insulator sandwiched therebetween as part of an electrode portion.
一般に液晶表示素子は、電極部を設けた電極基板を対向

なうものである。Generally, a liquid crystal display element has a structure in which electrode substrates with electrode parts are placed facing each other and a liquid crystal layer is provided between them.A voltage is applied between the electrode parts provided on the electrode substrates, and the voltage generated at that time is The desired display is performed by optical changes in the liquid crystal layer.
液晶層の厚みは、２μｍ以上、３０μｍ以下程以下用い
られ、その厚みを素子全面において均一にする必要があ

表示素子の大型化に伴ない、電極基板の面積が大きくな
り外力に依り液晶層の厚みの変化を生じ、液晶表示素子
として不都合な光学変化を生ずる。The thickness of the liquid crystal layer is approximately 2 μm or more and 30 μm or less, and it is necessary to make the thickness uniform over the entire surface of the device. In addition, the electrode substrate is usually less than 5 cm in thickness, and in particular,
As display elements become larger, the area of electrode substrates increases, causing changes in the thickness of the liquid crystal layer due to external forces, resulting in optical changes that are inconvenient for liquid crystal display elements.

る。Therefore, as a conventional method for making the thickness of the liquid crystal layer of a liquid crystal display element constant, glass beads with the same diameter as the thickness of the liquid crystal layer to be made constant are placed between the opposing substrates with the liquid crystal in between, or , a method is used in which the thickness of the liquid crystal layer is made constant by inserting spacers such as glass fibers to keep the spacing between the substrates constant. An example of this is shown in FIG. 1 is a substrate, 2 is a liquid crystal, 3 is a display electrode formed on the opposite surface of the substrate, 4 is a spacer such as glass beads or glass fiber, and 5 is an adhesive for sealing the substrate.

質に悪影響を及ばず。The method of dispersing the spacers 4 within the two liquid crystal layers is to disperse the spacers 4 in a solution such as alcohol and apply it onto the substrate 1, or to disperse the spacer 4 in a solution such as alcohol. A method is used in which spacers are attached to the surface of the substrate by dipping it and pulling it up. For this reason, it has the disadvantage that it requires a complicated process to uniformly disperse spacers such as glass beads and glass fibers on one surface of the substrate. Since the red color can only be seen by dispersing the spacers into the display pixels, there is a drawback that the spacers are dispersed over the display pixels and the dispersed portions of the spacers cannot be used for display. In particular, there is a need to improve the functionality of liquid crystal display elements, and display pixels are becoming increasingly finer, so if spacers are dispersed over a display pixel and display cannot be performed in that area, the screen will become darker. For example, on a 200 μm square pixel electrode,
When one μm glass fiber spacer was dispersed, the brightness was reduced by 2.5%, without any negative effect on image quality.

り、液晶層の厚みを一定にする構造としたものである。The present invention provides a liquid crystal display element having a laminated structure of a conductor with an insulator sandwiched between a part of the electrode part, in which the part where the conductor and the insulator are laminated is closer to the surface of the substrate formed in the electrode part. Focusing on this, we decided to avoid dispersing particles such as glass beads or glass fibers on the substrate surface in order to make the thickness of the liquid crystal layer constant, that is, the spacing between the substrates, as has been conventionally used. However, since the laminated part where the conductor and insulator are laminated, which is a necessary part for forming the electrode part, protrudes from the substrate in a protruding shape, this can be used to reduce the spacing between the substrates. By using part or all of the spacer to make the thickness constant, the thickness of the liquid crystal layer is made constant.

Scanning side conduction electrode 8 for
and the signal-side conductive electrode 9 must be formed to intersect with each other. However, if the signal side conductive electrode 9 and the scanning side conductive electrode 8 are electrically connected to each other at this intersection, it goes without saying that the liquid crystal panel cannot be driven. Therefore, on the electrode substrate, the signal side conductive electrode 9
At the intersection of the conductive electrode 10 and the scanning side conductive electrode 10, there is a 5L0 wire between them.
As a structure in which an insulator 10 such as No. 2 is formed, the signal side conductive electrode 9 and the scanning side conductive electrode 8 are electrically insulated.

A protruding portion 12 using a laminated portion of a conductor is attached to the upper substrate 1.
1, and the distance between the substrates does not narrow any further, so the protrusion formed at that time keeps the distance between the substrates constant,
Therefore, the thickness of the liquid crystal layer is made constant.

を得ることができる。In the case of the quadruple matrix liquid crystal panel shown here, the screen size is 45 B x 60 tm, and the number of pixels is 120.
The LCD panel has 160 dots and 160 horizontal dots (total 19,200 points).
Spacers using laminated parts according to the present invention can be formed at 9,600 points within a screen. This allows spacers to be formed over the entire area of the screen at a pitch of 0.75 m vertically and 0.375 m horizontally to keep the substrate spacing constant. The spacer is not on the display pixel electrode,
Since all the electrodes are formed in areas other than the display pixel electrode, there is no problem that the area of the display pixel becomes smaller due to the formation of the spacer. Furthermore, since the liquid crystal layer is formed at a uniform pitch over the entire surface of the liquid crystal panel, even when applied to a large-sized liquid crystal display element, a liquid crystal layer with a uniform thickness can be obtained over the entire surface.

Rather than further laminating an insulating layer on the laminated portion of the conductor wiring, an insulator is placed on the signal side conductive electrode 9 of the other substrate 11 that faces the laminated portion of the conductor wiring on one substrate with the liquid crystal layer in between. 13 is provided, and when both substrates form a liquid crystal cell, the protrusions 13 protruding from the display pixel portion to the liquid crystal layer side come into contact as shown in FIG.
Therefore, the distance between the side substrates, that is, the thickness of the liquid crystal layer is made constant depending on the sum of these heights.
本実施例によれば、基板上の突起部分の高さを液晶層の
厚みの半分程度とすることができるという効果がある。According to this embodiment, there is an effect that the height of the protruding portion on the substrate can be made approximately half the thickness of the liquid crystal layer.

であるという効果がある。However, the laminated portion at the intersection of the scanning side conduction electrode and the signal side conduction electrode on one substrate and the insulator formed on the signal side conduction chamber/top of the other substrate can be formed on the same substrate. Therefore, it is possible to form the insulating layers on these protruding portions at the same time, and the formation process is simple.

That is, the protruding portion for making the thickness of the liquid crystal layer constant is placed on the insulator 12 on the layered structure portion 10 of the conductor on one of the substrates.
are further laminated, and an insulator 13 is laminated on the conductor wiring portion of the other substrate opposite to the laminated portion of the former substrate, thereby making the thickness of the liquid crystal layer constant.

果がある。According to this embodiment, the insulator 10 used in the laminated structure of the conductor
The height of the insulating layer 12 need only be considered to be sufficient for insulation between the conductors, and this has the effect that the thickness of the liquid crystal layer can be regulated by the height of the insulating layer 12 that is further laminated.

This has the advantage that there is no need to specially form an insulator on the opposing portions of one substrate.
