Abstract: An LED display device including: a bottom case, electronic components, a circuit board, and an LED lamp group, with no mask covering above the LED lamp group. A cured resin layer is potted over the LED lamp group fixed on the circuit board, and the cured resin layer is adhered with a light-transmitting film, and the cured resin layer and the light-transmitting film together serves as a protective layer. The LED display device has advantages in adjusting and controlling the contrast, viewing angle, and color uniformity of the display device; the performance in moisture proof, windproof, rainproof, anti-corrosion, heat dissipation, and ultraviolet resistance is obviously improved, which can significantly reduce the lamp dysfunction rate and lamp collision rate of the display device, prevent the lamp bead from falling off and avoid other damage to the lamp bead, thereby making the maintenance procedure simpler.
