Polyimide‐free technology is a technology in which an additive can replace polyimide film to align LC molecules. In this technology, the additive added in liquid crystal (LC) host can not only affect the alignment behavior, but also affect the reliability of the panel, such as image sticking. Because the polymer is polymerized from the additive in LC, the system of the additive is very important. In this paper, we studied the alignment and image sticking performance fabricated by two different additive systems:1. the mixed system of additive and reactive monomer; 2. the single additive system. From the results of cell and 28” panel, we can conclude that the mixed system has similar alignment ability and voltage holding ratio to the single additive system, however, has better image sticking performance than the single additive system.
