In this paper we succeeded to develop a approach by using new material, named gray bump in stead of current bump material to achieve excellent contrast ratio(CR) of liquid crystal display(LCD) at normal direction for MVA mode. Meanwhile, we needn't change any processes, and surely no additional cost. Except CR enhancement at normal direction, it can also reduce the oblique light leakage of dark state and improve the viewing angle. We evaluate the response time and reliability for image sticking of this new bump design and it has the similar response time and image sticking performance as the original bump design. Finally, we also show the CR >3000:1 32″ TV that adopting this new design and using higher CR polarizers with lower haze value surface treatment.
