PROBLEM TO BE SOLVED: To provide a light emission display device in which a light emission state is easily and visually recognized even from a remote position, overlooking by a dead angle is hardly generated, there is no deterioration of a light emitting part by exposure to water, etc. and durability of a control mechanism part is successful in the light emission display device which reports a state change of a detection object by light emission of a luminous object. SOLUTION: The light emission display device is constituted so that light irradiated from the luminous object 5 is reflected on an irregular reflection surface 6 by providing a protection cover 12 consisting of an optical transmission hard material for covering an attached part of the light emitting diode 5 and forming the irregular reflection surface on at least a part of the inner surface side of the protection cover 12.
