Abstract
The reflective type color filter for the liquid crystal displays (LCDs) was produced using cholesteric liquid crystal monomers whose phase is characterized by the unique optical features of selective reflection. Periodic micrometer scale hemi-spherical photoresist (PR) patterns were formed on glass substrates by thermal reflow method after photolithography. Cholesteric color filter films for red, green, and blue light reflections were then produced and the viewing angle dependence was investigated and compared with that of reflected light on the non-patterned substrates. Computer simulations using "LightTools" were also carried out, and it was confirmed that the color shifts were much smaller on the patterned substrates by bare eyes and Commission Internationale de'Eclalrage (CIE) chromaticity coordination analysis qualitatively.
