ABSTRACT:
A method for manufacturing a light shielding layer for a liquid crystal display device having a substrate includes the steps of forming a color filter layer including RGB colors on the substrate and coating a first light shielding material on the color filter layer and the substrate. A first back exposure is performed to form first hardened portions and first unhardened portions of the first light shielding material, and the unhardened portions are developed. A second light shielding material on the color filter layer and the first light shielding material. A second back exposure is performed to form second hardened and second unhardened portions of the second light shielding material, and the second unhardened portions are developed.
