Abstract
The present disclosure discloses a color film substrate, a display panel and a display device. The color film substrate includes a substrate; a light shielding layer on the substrate, wherein the light shielding layer is provided with a plurality of pixel openings and is configured to block visible light and transmit infrared light so as to be multiplexed as a black matrix, and infrared light transmittance of the light shielding layer is greater than infrared light transmittance of the black matrix; and a color resist layer on a side, away from the substrate, of the light shielding layer, wherein the color resist layer includes a plurality of color resists, and each of the color resists respectively corresponds to one of the pixel openings and extends from the corresponding pixel opening to a surface, away from the substrate, of the light shielding layer.
