Color filter for a reflective type LCD and method for manufacturing the same
The present invention relates to a method for manufacturing a color filter. The method utilizes the dry film technology, photomasks, exposure and development process to form the black frame, the red pixel array and the green pixel array on the substrate. Finally, the blue pixel array is formed on the substrate by utilizing a back mask, exposure from a backside of the substrate and development process. Therefore, the red pixel array and the green pixel array on the substrate can cut the UV exposure from backside. In the exposure process, only the blue pixel array in a recess area exposes under the UV light. After the development process, the blue pixel array is formed on the substrate.
