Abstract
A color filter substrate is provided with a layered structure containing monocolor quantum dots in areas of sub-pixels of at least one color of the pixels, and the layered structure is formed by laminating flake graphene layers and monocolor quantum dot layers alternatively. The color filter substrate can efficiently convert background light into monochromatic light, can increase the color gamut of the liquid crystal display panel, enhances color saturation, and improves display quality of the display screen.
