The invention provides a
color film substrate, a manufacturing method of the
color film substrate, a display panel and a
display device. The
color film substrate comprises a substrate body, single-layer color film
layers and a color folding film layer, wherein the single-layer color film
layers are formed on one side of the substrate body and located in color sub-pixel areas, and the color folding film layer is located between one part of the color sub-pixel areas and formed by multiple single-layer color film
layers in a laminated mode. The color film substrate further comprises a shock insulator located between the other part of the color sub-pixel areas and an
auxiliary electrode layer with which the surface of the color folding film layer is covered. The top surface of the shock insulator is higher than that of the color folding film layer, and the shock insulator can be elastically compressed in the height direction. The situation that the color film substrate cannot be used normally due to uneven
internal pressure when a screen is oversize is avoided, the color film substrate is applied to display of OLEDs, damage to ITO materials and
cathode materials of the
auxiliary electrode layer can be effectively reduced, and a good electric conduction effect can be guaranteed.
