Characterization of multi-domain bumps of organic resists in color filters for wide-viewing-angle liquid crystal displays

The negative-type multi-domain vertical alignment(MVA) photoresist have been significantly synthesized and potentially integrated in the processing of color filter for the application of wide-viewing-angle liquid crystal display. The expectable results including excellent light transmittance, stability and uniformity of protrusion bumps in shape, superior reliability in material characteristics and wider gamut have significantly been achieved. The brightness of negative-type photoresist(NPR) is superior to that of positive-type photoresist(PPR) as a result of NPR owing excellent transmittance. The transmittance of protrusions of positive-type photo resist and negative-type photo resist is 70 % and 100%, respectively.
