Abstract
Perfluorocyclobutane aromatic ether polymer (PFCB) is being researched as a planarization resin for color filters and active devices for flat panel displays. In addition, the material is being evaluated as the alignment layer as well as the color filter binder and the results will be reported here in. The results of the current study have shown PFCB to exhibit superior planarization to polyimide with efficiencies <90%. As an example, a typical 1.5 micrometers P-V (Peak-Valley) of a color filter can be reduced to about 120 nm with the application of about 5 micrometers of PFCB. In addition to efficiently smoothing color filter type patterns, the PFCB is being explored as a binder resin for the dye or pigment.
