Color film substrate, display panel and display device

A display device, comprising:

• a backlight module;
• a display panel on a light emergent side of the backlight module;
• an infrared light source at an end of the display panel;
• and a fingerprint recognition module on a side, away from the display panel, of the backlight module, wherein:
• the backlight module is provided with a via hole in an area corresponding to the fingerprint recognition module;
• and after infrared light emitted by the infrared light source is reflected by fingers, the reflected infrared light is irradiated to the fingerprint recognition module through the display panel and the via hole;
• A the display panel, comprising:
• an array substrate;
• a color film substrate opposite to the array substrate;
• and a liquid crystal layer between the array substrate and the color film substrate;
• the color film substrate, comprising:
• 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 comprises 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.
