Wide Viewing Angle TFT-LCD with Single Orientation Film

摘要

The present invention relates to a wide viewing angle TFT-LCD having a single alignment film having a wide viewing angle by forming a single alignment film on a transparent substrate and rubbing at different angles.;The present invention relates to a liquid crystal display device in which a color filter substrate and an alignment film formed on a TFT substrate opposite to the color filter substrate are used as a single alignment film and a spiral dopant for twisting the liquid crystal in a predetermined direction is added to the liquid crystal injected therebetween, , And the single orientation layer was rubbed twice with the first rubbing alignment layer having different rubbing directions.;Thus, the same effect as that of using two alignment films different in the conventional pre-tilt angle has been obtained.;Thereby, there is an advantage that limitation of the selection of the alignment film material is reduced and the process is simplified.;The rubbing directions of the first rubbing orientation film and the second rubbing orientation film formed on the light-transmitting substrate are different from each other and have a wide viewing angle with no phenomenon such as brightness reversal at a wide angle comparable to the TFT-LCD using the conventional DDTN method There is an advantage that a TFT-LCD can be realized.
