Touch-related information which cannot be acquired by the naked eye (dubbed here as sub-optical pattern information) has its corresponding sub-optical patterns respectively positioned within the aperture areas of respective domains such that the displayed image, as viewed from different viewing angles is not adversely affected by the embedded sub-optical patterns. One type of touch-related information which can be conveyed is that of touch location of a sub-optical pattern sensing pen positioned over one or more of the sub-optical patterns.
