Zusammenfassung:PROBLEM TO BE SOLVED: To solve the problem that sufficient cleaning of the surface of a LED can not be performed because an eaves-like member interferes since the eaves-like member is formed on the front surface by projecting long in the conventional LED display unit. SOLUTION: In the LED display unit, a printed circuit board 2 on which LEDs 3 are arranged like a matrix is attached to a casing 1, a hole 51 into which a middle part of the LEDs is inserted at a contact state is formed on the front surface side of the printed circuit board and a light shielding member in which louvers 53 are formed along columns of the LEDs is arranged, a transparent board 6 is attached to a peripheral wall of the light shielding member at a watertight state at a state that the LEDs projecting on the side of the light shielding member are covered.
