Abstract
The method includes the following steps. The transparent base plate is provided and there are the multiple black matrices on the plate. The multiple obstructing walls are formed on the black matrices. Each width of the obstructing wall is less than the width of the black matrix. The multiple micro flow liquids with different required colors are filled into the places between each obstructing walls. The multiple micro flow liquids between obstructing walls are blended into the ink. Then following procedures are carried out: solidifying the inks with different color in each wall so as to form the required color, removing the walls on the black matrices, forming the transparent conducting layer to cover the black matrices and the color layer. The obstructing walls prevent the inks with different color to generate the color mixture.
