ABSTRACT:
The present invention provides a color filter structure and a forming the same method. The structure comprises a transparent substrate, a black matrix and a plurality of color regions separated by the black matrix. The black matrix grid is formed by a plurality of horizontal black matrix strips crossing a plurality of vertical black matrix strips. These color regions are formed by red, green or blue color resin forming in corresponding matrix grids. In each matrix grid, the resin is positioned to cover a larger area on an adjacent vertical black matrix strip than to cover an area of the other adjacent vertical black matrix strip. The structure can prevent the problem of corner image sticking in a frame of the liquid crystal display device.
