本発明は、液晶ディスプレイを構成するための液晶セル
に関する。DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a liquid crystal cell for constructing a liquid crystal display.
(従来の技術)
液晶セルにおいては、基板の間隔、即ち、セルキャップ
を一定に設定し、均一な厚さで液晶層を設けることが必
要であり、これにより画像の優れた液晶ディスプレイが
得られる。(Prior art) In a liquid crystal cell, it is necessary to set the spacing between the substrates, that is, the cell cap, to a constant value, and to provide a liquid crystal layer with a uniform thickness.This makes it possible to obtain a liquid crystal display with excellent images. .
第3図には従来の液晶セルの一例が示されている。即ち

板より成る一対の基板1.1を備え、これら基板1.1

1間にセルキャップgを形成している。FIG. 3 shows an example of a conventional liquid crystal cell. That is, this liquid crystal cell includes a pair of substrates 1.1 made of glass plates or transparent plastic plates.
A spacer 2 is arranged in between, and a liquid crystal 3 is sealed. Spacer 2 is made of glass fiber, and substrate 1.
A cell cap g is formed between 1 and 1.
(発明が解決すべき問題点)
しかし、ガラスファイバーより成るスペーサ2を用いて
セルキャップgを形成する場合には、二足上のスペーサ
2が重なり合うことがあるので。(Problems to be Solved by the Invention) However, when forming the cell cap g using spacers 2 made of glass fiber, two spacers 2 may overlap.

の厚さがスペーサ2の重なりで局部的に大きくなってい
るので、同様に良好な画像が得られない。Since the thickness of the cell gear, that is, the thickness of the liquid crystal layer varies from liquid crystal cell to liquid crystal cell, and it is difficult to arrange the spacers 2 at equal intervals, the spacing between the spacers also varies. Therefore, when a large-screen liquid crystal display is constructed using a large number of such liquid crystal cells, image deterioration becomes particularly significant because the thickness of the liquid crystal layer and the spacer interval are different in each liquid crystal cell. Furthermore, when a flexible liquid crystal display is constructed using a liquid crystal cell having a plastic substrate, the thickness of the liquid crystal layer of the liquid crystal cell is locally increased due to the overlap of the spacers 2, so that similarly good images cannot be obtained. I can't get it.

Transparent display electrodes 10A and IIA are provided on opposing surfaces of each of these substrates 10.11. A plurality of spacers 13 having a rectangular cross section are arranged at predetermined intervals between the substrates 10 and 11.

スプレイを構成する場合には、良好な画像が得られる。In this way, by forming the spacers 13 from photosensitive resin by molding a predetermined pattern, not only can each spacer 13 be formed to have the same dimensions, but also the spacers 13 can be maintained at a predetermined distance from each other to ensure their overlapping. can be prevented. Therefore, the cell gap g between the substrates 10.11
' is uniquely determined by the height dimension of the spacer 13 over the entire surface, so that the thickness of the liquid crystal layer 14 becomes uniform throughout. Therefore, when a large-screen liquid crystal display is constructed using the liquid crystal cell of the present invention, a good image can be obtained.
また、スペーサ13間隔及びその高さ寸法を任意に設定
