Abstract
In summary, when the alignment layer aligns the adjacent liquid crystal molecules while producing the pretilt, the present invention basically forms a different pretilt of the alignment layer of the upper substrate or the alignment layer of the lower substrate, or basically forms a different pretilt of the alignment layer of the high gray subpixel and the alignment layer of the low gray subpixel in one pixel, and as a result, the visibility is improved in the sides (the upper side or the right and left sides).
