Color film substrate, display panel and display device

In the color film substrate, the display panel and the display device provided by the utility model, the color film substrate comprises a first substrate, and the first substrate comprises a display area and a first frame area wound around the display area; the conductive layer is positioned on one side of the first substrate; the first polaroid is positioned on one side, far away from the first substrate, of the conductive layer; on the side where the first frame area is located, the orthographic projection of the first polaroid on the plane where the first substrate is located covers the orthographic projection of the conductive layer on the plane where the first substrate is located; the first shading structure is located between the conductive layer and the first polaroid; the orthographic projection of the first shading structure on the plane where the first substrate is located is at least partially overlapped with the first frame area.
