The present invention provides an oriented organic thin film, a liquid crystal display device with the oriented organic thin film and a thin and flexible liquid crystal display device.
The organic thin film is obtained by spreading an organic substance comprising a polymer on a liquid surface, and compressing the spread substance unidirectionally or in two directions facing each other. In this organic thin film the principal chain of said polymer in the surface of the film is oriented perpendicularly to the direction of the compression. The liquid crystal display device comprises substrates (12, 18), a polarizer (11, 19), electrodes (13, 17) at least one of which is transparent, if necessary semiconductor substrates at least one of which is transparent, an orientation-controlling film (14, 16) and a liquid crystal layer (20), wherein at least one of the polarizer, electrode, semiconductor substrate, orientation-controlling film and liquid crystal layer comprises an organic thin film. The orientation-controlling film (14, 16) may be an organic thin film in which the film-forming molecules have been uniformly oriented in a particular direction in the surface of the film.
本发明提供了一种取向有机薄膜、一种带有取向有机薄膜的液晶显示装置和一种轻薄柔性液晶显示装置。
这种有机薄膜是通过在液体表面铺展由聚合物组成的有机物,并单向或双向压缩铺展物而得到的。在这种有机薄膜中,所述聚合物在薄膜表面的主链方向与压缩方向垂直。液晶显示装置包括基板(12,18)、偏振片(11,19)、电极(13,17)(其中至少有一个是透明的),必要时还包括半导体基板(其中至少有一个是透明的)、取向控制膜(14,16)和液晶层(20),其中偏振片、电极、半导体基板、取向控制膜和液晶层中至少有一个包括有机薄膜。取向控制膜(14、16)可以是一种有机薄膜,其中成膜分子在薄膜表面沿特定方向均匀取向。
