ABSTRACT:
The color filter of the present invention comprises ink films colored by ink drops140inside openings111enclosed by banks112demarcated and formed on a substrate110.The banks112have a laminar structure comprising a metal film120and a photosensitive organic thin film130from the substrate110side. 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.
