The invention discloses a flexible transparent LED display with the bending degree not smaller than 85 degrees, and relates to the field of LED displays. The flexible transparent LED display comprisesa modified PET film layer, a plurality of first copper plating layers distributed in a rectangular array are arranged on one side of the modified PET film layer, low-temperature solder paste layers are welded to the outer sides of the first copper plating layers, and SMT lamp beads are fixedly connected to the outer sides of the low-temperature solder paste layers. A protective layer is coated between every two adjacent low-temperature solder paste layers, and a second copper plating layer is arranged between every two adjacent first copper plating layers. The first copper plating layers andthe second copper plating layers are arranged on the modified PET film layer, the multiple tooth grooves are formed in the conductive adhesive layer above the second copper plating layers, and the arc-shaped grooves are formed
