An LED(Light Emitting Diode) display device for a multi-vision is provided to minimize the weight and volume by forming a space between a PCB(Printed Circuit Board) and a PCB protection cover and to secure free arrangement without the limitation of an installation space by transmitting the sound or light through a gap formed at a frame. A fixing frame(1) perforated to transmit the light, sound, and wind includes: a sill unit(17) formed inside along a rim(18) to combine and support a plate-shaped PCB(2) and a PCB protection cover(3) on the front side; combining holes(11) aligned on the sill unit at regular intervals to join the PCB and the PCB protection cover; and plural horizontal pieces(6) and a center vertical piece(5) connected with the sill unit to partition and support the inside of the bored hole. A power supply unit case(7) is installed in the back side center of the fixing frame to install an LED display device(100) in a circular form and composed of a power supply unit(8) connected with the PCB to supply power to an LED(4) and an input/output unit(14) inputting and outputting the data, formed like a ladder by forming symmetrical inclined surfaces on both ends, and joined with the combining hole of the fixing frame by a bolt. The PCB protection cover has plural PCB protection pieces bored at the same intervals as LED combining pieces(16) to protect the front side of the PCB and transmit the light and sound, and combining holes formed along the edge correspondently to the combining holes of the sill unit of the fixing frame.
