PROBLEM TO BE SOLVED: To provide a railroad crossing display device which can be inexpensively installed and can arouse existence of the crossing for vehicles or pedestrians or the like that reliably cross the crossing even in the night. SOLUTION: Since the number of LEDs 2 to be used can be reduced by using a light guide plate 3 emitting the light in a plane from both surfaces, and the display on both surfaces can be performed by an integral display device 10, the railroad crossing display device can be inexpensively installed. Since the light can be emitted from the LEDs 2 by a storage means 5, the display means can arouse the existence of the crossing for vehicles or pedestrians or the like that reliably cross the crossing even in the night.
