Abstract
A color filter having two-layered light-shielding sections without a black matrix is provided, which reduces the level difference from the colored materials for pixels with a simple method and makes it possible to remove the color layer on the said sections. A red color layer having stripe-shaped red pixel formation sections and a blue color layer having stripe-shaped blue pixel formation sections are overlapped to form two-layered light-shielding sections. A green color layer having island-shaped green pixel formation sections is overlapped with the red and blue color layers, placing the green pixel formation sections in the overlapped green pixel windows of the red and blue color layers. Only the peripheries of the green pixel formation sections are placed on the light-shielding sections to facilitate the removal of the peripheries by polishing.
