Cholesteric liquid crystal color filter and process for producing the same

摘要

The present invention provides a cholesteric liquid crystal color filter including partition walls that are formed at pixel boundaries, produced by: forming a liquid crystal layer comprising a cholesteric liquid crystal composition including at least a liquid crystal compound, a photoreactive chiral agent and a polymerization initiator; and irradiating the liquid crystal layer with UV light having wavelengths to which the polymerization initiator is photosensitive through a photomask to form the partition walls at areas corresponding to the pixel boundaries while the liquid crystal layer is in an isotropic liquid state or in a cholesteric state not exhibiting selective reflection of light in the visible range. The invention also provides a process for producing a cholesteric liquid crystal color filter including openings that are formed at positions corresponding to at least contact holes and/or electrode lead-out portions.
