Orientation method of ECB mode liquid crystal cell and manufacturing method of multi-domain ECB mode liquid crystal cell using same

摘要

It is an object of the present invention to provide a method for obtaining a liquid crystal cell of vertical alignment ECB mode having high contrast ratio, wide viewing angle, and stable gray scale in optical alignment.;The present invention for achieving the above object is the step of applying the alignment film of the photosensitive polymer having a vertical alignment property different from the conventional alignment film material and the pre-tilt angle forming characteristics on the first substrate and the second substrate, having the vertical alignment Irradiating light on the first substrate and the second substrate to which the alignment film of the photosensitive polymer is coated to determine pretilt having a large pretilt of 50 ° or more on the first substrate and the second substrate, wherein the first substrate faces the alignment film. And bonding the second substrate; And injecting a liquid crystal having negative dielectric anisotropy between the first substrate and the second substrate.
