Patent ID: 7615320

Claim:
A method for fabricating a color filter substrate comprising: preparing a mask having a first exposure part, a second exposure part and a third exposure part; positioning the mask above a film, wherein the film is horizontally divided into four region that a first region, a second region, a third region and a fourth region; forming a first image in the first region by irradiating visible rays of a first wavelength onto the first region of the film through the first exposure part of the mask and by shifting the second exposure part and the third exposure part of the mask; forming a second image in the second region by irradiating visible rays of a second wavelength onto the second region of the film through the second exposure part of the mask and by shifting the first exposure part and the third exposure part of the mask; forming a third image in the second region by irradiating visible rays of a third wavelength onto the third region of the film through the third exposure of the mask, wherein the fourth region of the film between each of the first region, second region and third region is not irradiated by the visible rays, is formed of a black matrix; and forming film-type color filter layers by developing the film having the first, the second and the third images, wherein the first, the second and the third images are on the same plane, wherein the film-type color filter has a flat surface.
