Abstract
A method for manufacturing a color filter is provided, including: preparing a photomask comprising a plurality of pixel units, the pixel units each comprising red, green, and blue color resist layers; preparing a first substrate coated with a photosensitive polyester layer; exposing the first substrate by a light source irradiating through the photomask, so that color resist elements of different colors are formed on the first substrate from reaction of light passing respectively through the red, green, and the blue color resist layers with the photosensitive polyester layer; and developing the first substrate and washing part of the first substrate that is not exposed. The method for manufacturing the color filter is simple in technique, thereby effectively reducing the production cost of the color filter.
