Claims
- 1. A method for making a color filter, comprising the steps of:
- measuring a temperature of a substrate by a plurality of thermocouples directly applied to plural points of the substrate;
- forming a colored organic polymer film on the substrate by applying a solution comprising a polyamide resin and a colorant onto the substrate using a flexographic apparatus comprising a cylinder and a plate held on said cylinder, said plate having a relief pattern for printing on the substrate, said flexographic apparatus further comprising a stage for supporting the substrate, a rectangular groove formed within the stage adapted to provide a vacuum therein and secure the substrate to the stage, and a temperature control means embedded within the stage for controlling the substrate at a prescribed temperature from 30.degree.-50.degree. C., said temperature control means including a path for circulating liquid having a controlled temperature, wherein
- said organic polymer solution is applied onto the substrate while the substrate is controlled within the prescribed temperature.
- 2. A method for making a color filter, comprising the steps of:
- selecting a substrate with a color filter layer;
- measuring a temperature of said substrate by a plurality of thermocouples directly applied to plural points of the substrate;
- forming an organic polymer film on the substrate by applying a solution comprising a photosensitive phenol-novolak resin onto the substrate using a flexographic apparatus comprising a cylinder and a plate held on said cylinder, said plate having a relief pattern for printing on the substrate, said flexographic apparatus further comprising a stage for supporting the substrate, a rectangular groove formed within the stage adapted to provide a vacuum therein and secure the substrate to the stage, and a temperature control means embedded within the stage for controlling the substrate at a prescribed temperature from 30.degree.-50.degree. C., said temperature control means including a path for circulating liquid having a controlled temperature, wherein
- said organic polymer solution is applied onto the substrate while the substrate is controlled within the prescribed temperature.
