ーサーが移動してしまうこともあった。A spacer made of plastic beads, glass fiber, etc.; 5, a liquid crystal sealed between the transparent electrodes 2 by a seal 6; 7, a polarizing plate disposed outside the substrate 1; In a liquid crystal display element with such a configuration, it is difficult to uniformly disperse the spacers 4, and the spacers are dispersed unevenly, which may result in uneven display. This reduces production efficiency and causes defects, and in the case of flexible liquid crystal cells that use plastic thin film substrates, the spacer may move internally. .
本発明は、以上の点に鑑み、一様な表示品質が得られ且

いる液晶表示素子を提供することを目的としている。In view of the above points, it is an object of the present invention to provide a liquid crystal display element that can provide uniform display quality, does not require a dispersion process, and can securely hold spacers.

により解決される。This purpose was achieved by using a liquid crystal display element composed of a plastic substrate, in which spacers for maintaining uniform spacing between transparent electrodes are integrally molded on one side of the substrate in a uniformly dispersed state. This problem can be solved by a liquid crystal display element.
以下図面に示した実施例に基づき本発明を説明すれば、
１１は一様に分散した状態で一体成形された例えば円柱

第１図の従来例と同様である。The present invention will be explained below based on the embodiments shown in the drawings.
Reference numeral 11 denotes a substrate having, for example, cylindrical spacers 11a integrally molded in a uniformly dispersed state, and the other structure is the same as that of the conventional example shown in FIG.
本発明実施例は以上のように構成されているから、その
動作は第１図に示された従来の液晶表示素子と全く同様

された状態で基板の一方１１に一体成形されている。Since the embodiment of the present invention is constructed as described above, its operation is performed in exactly the same manner as the conventional liquid crystal display element shown in FIG. 1, and the spacers 11a are uniformly distributed in advance. It is integrally molded on one side 11 of the substrate in a state of being held.

A transparent electrode 2 and an alignment treatment agent 3 are arranged at the tip of the
As shown in Fig. 4, the alignment treatment agent 3 is attached to the tip of the spacer 11a.
There is also a spacer with a 5th spacer shape.
Modifications such as a hemispherical shape as shown in the figure or a cylinder with a rounded tip as shown in FIG. 6 are possible.

尚、本発明は、ＴＮ形、ＧＨ形等のすべての形式の液晶
表示素子に適用し得るものである。As described above, according to the present invention, since the spacers are uniformly distributed in advance and integrally molded on one side of the substrate, the interval between the transparent electrodes is always maintained uniformly, so stable unevenness can be achieved. This eliminates the need for a spacer dispersion process, which eliminates a decrease in production efficiency and reduces costs.Furthermore, spacers can be moved even in the case of flexible liquid crystal cells. Furthermore, the present invention can be applied to all types of liquid crystal display elements such as TN type and GH type.
