CF substrate, CELL liquid crystal box, display panel and display device

The utility model relates to the field of liquid crystal displays and columnar gaskets, and discloses a CF substrate, a CELL liquid crystal box, a display panel and a display device. The CF substrate comprises a substrate base plate, a first electrode and a second electrode, the BM layer is arranged on the substrate; the RGB layers are arranged at the hollowed-out positions of the BM layer at intervals; an OC layer disposed on the BM layer and the RGB layer to cover the BM layer and the RGB layer; the columnar gasket is positioned on the OC layer and is used for supporting the CF substrate; wherein the columnar gasket is made of an alloy material. The LC Margin is added in the box forming process, so that the uniformity of Cell Gap and the yield of PPI products are improved, the phenomena of black Gap, high-temperature mura, low-temperature Bubble and the like caused by external force application after box forming can be avoided, and the reliability of the products is improved.
