PHOTOSENSITIVE COLOR COMPOSITION FOR COLOR FILTER OF TRANSFLECTIVE LIQUID CRYSTAL DISPLAY, METHOD FOR MANUFACTURING COLOR FILTER USING THE COMPOSITION, COLOR FILTER MANUFACTURED BY THE METHOD, AND THE TRANSFLECTIVE LIQUID CRYSTAL DISPLAY DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a method for easily and inexpensively manufacturing a color filter with high productivity, the color filter for a transflective liquid crystal display capable of performing transmissive color display and reflective color display with superior lightness and color saturation.;SOLUTION: A photosensitive color composition is disclosed, containing an organic pigment having an average primary particle diameter of 5 to 60 nm; a photopolymerization initiator, having a wavelength m where the molar extinction coefficient reaches the maximum in a range of 300 to 370 nm and a molar extinction coefficient m range of 8,500 to 80,000 L/mol cm at a wavelength m; an ethylenically unsaturated monomer; a binder resin; and a solvent. The method for manufacturing a color filter includes steps of forming a coating film of the photosensitive color composition on a transparent substrate; and forming a color layer for a light-transmitting region and a color layer for a light-reflecting region, by having the coating film irradiated with UV rays via a photomask and developing, the photomask having a full light-shielding region, a translucent light-shielding region having a transmittance range of 20 to 50% at 365 nm wavelength, corresponding to the formation of a color layer in the light-reflecting region, and a full transmission region corresponding to the formation of a color layer in the light-transmitting region.;COPYRIGHT: (C)2010,JPO&INPIT
