摘要:
The color filter of the present invention comprises ink films colored by ink drops 140 inside openings 111 enclosed by banks 112 demarcated and formed on a substrate 110. The banks 112 have a laminar structure comprising a metal film 120 and a photosensitive organic thin film 130 from the substrate 110 side. The inks should contain a solvent having a high boiling point. The bank layer may also be configured so that the peripheral edges of the bottom surface thereof are positioned inside from the peripheral edges of the light blocking layers, so that the light blocking layers have exposed surfaces on the upper surface thereof where the bank layer is not superimposed. Thus color filters can be provided which exhibit outstanding contrast without coloring irregularities.
