A color film substrate includes a substrate and a color resist layer arranged on the substrate. The color resist layer includes red, green and blue color resist areas. The color film substrate further includes a light absorption layer located on the substrate, the color resist layer and the light absorption layer being arranged in sequence in a light output direction. The light absorption layer includes first to third light absorption areas. The first to third light absorption areas are disposed corresponding to the red, green and blue color resist areas, respectively. The first light absorption area absorbs near-infrared light transmitted by the red color resist area. The second light absorption area absorbs yellow light transmitted by the green color resist area. The third light absorption area absorbs short-wave blue light transmitted by the blue color resist area.
