Liquid crystal display device having characteristic of viewing angle which is right-and-left symmetrical and up-and-down symmetrical

摘要

In a liquid crystal display device comprising first and second substrates having first and second principal surfaces which are opposed to each other with a space left therebetween, first and second alignment layers are formed on the first and the second principal surfaces of the first and the second substrates. The first alignment layer is subjected to a first aligning treatment in a first aligning treatment direction while a second alignment layer is subjected to a second aligning treatment in a second aligning treatment direction which shifts from the first aligning treatment direction by a predetermined slight angle. Interposed between the first and the second alignment layers, a liquid crystal layer comprises a plurality of liquid crystal molecules each of which is twist aligned by a twist angle equal to the predetermined slight angle.
