ABSTRACT:
The present invention provides a method for manufacturing a color filter to facilitate the correction of the defect which is caused by the undesirable mixing of plural color filter materials with different color. Further, the present invention provides a color filter manufactured by the present method for manufacturing the color filter and also a semiconductor device using the color filter manufactured by the present method. In the manufacturing method of the present invention, the color-mixed portion which is undesirably formed during the production of the color-filter by using a plurality of color filter materials is irradiated with a laser beam which is different in transmissivity to each color filter material. This method allows the color filter material which is necessary to remain and the color filter material which is unnecessary to be selectively removed.
