When a drive circuit was connected between the electrode 9 and the scanning electrode 9, and multiplex driving was performed at ±100 square meters (duty ratio 1/400), a clear display with a contrast ratio of 10 or more was obtained. According to this method, a multiplex drive liquid crystal display device using a varistor film as a nonlinear element can be easily obtained.
Moreover, since it has stable characteristics with little variation in film thickness, it can be used as a display device for large screens. In addition, by printing and baking the varistor film not over the entire substrate as in the conventional case but only between the pixel electrodes and the scanning electrodes, it is possible to perform a transmissive display, which was previously impossible. Although the explanation has been made by specifying the scanning electrode 9 and the scanning electrode 9, the signal electrode 6 may be driven as a scanning electrode, and the scanning electrode 9 may be driven as a signal electrode.

Since the liquid crystal is dispersed between thermoplastic resins, there is no need for a solvent removal operation, which makes it easy to control the thickness of the medium layer, and the surface of the medium layer is smooth, so it does not deteriorate the operation of the liquid crystal display device. There will be no deterioration in performance, such as damage or shortening of service life. Further voltage 0N-OF
It has a high contrast ratio at F, and can be suitably used as a large-screen liquid crystal display device.
また接着剤を使用せずに、媒体層と透明電極面とを貼り
合わせることもできる。It is also possible to bond the medium layer and the transparent electrode surface together without using an adhesive.
