    • A liquid crystal display element of the type having a pair of transparent electrodes consisting of a pair of glass substrates and liquid crystal charged in the space therebetween and which is completely free from a so called "touch", a phenomenon that can destroy the orientation films of the element, is disclosed. According to the invention, a liquid crystal display element of the type as described above is provided with a first insulating film made of a single crystal material having a refractive index greater than that of the transparent electrodes of the glass substrate of the crystal display element. The first insulating film is disposed between one of the transparent electrodes and its corresponding orientation film and a second insulating film made of a single crystal material having a refractive index smaller than that of the transparent electrodes between the other electrode and its corresponding film. The insulating film are so selected that the average value of the refractive index of said first insulating film and that of said second insulating film is substantially equal to the refractive index of the transparent electrodes.
    • 一种具有一对透明电极的液晶显示元件,该透明电极由一对玻璃基板和装在它们之间的空间中的液晶组成,并且完全没有所谓的“触摸”,这可能会破坏取向膜 的元素。 根据本发明,上述类型的液晶显示元件设置有由具有大于晶体显示元件的玻璃基板的透明电极的折射率的单晶材料制成的第一绝缘膜。 第一绝缘膜设置在透明电极和其相应的取向膜中的一个和由另一电极和其相应的膜之间具有比透明电极的折射率小的单晶材料制成的第二绝缘膜。 选择绝缘膜,使得所述第一绝缘膜和所述第二绝缘膜的折射率的平均值基本上等于透明电极的折射率。
