PROBLEM TO BE SOLVED: To provide a stereoscopic display device of IP system capable of displaying a stereoscopic image in a distributed manner, and a stereoscopic display system comprising the stereoscopic display device.SOLUTION: A stereoscopic display system comprises a marker 2 configured to define a coordinate system of a space that reproduces a stereoscopic image, and a plurality of stereoscopic display devices 1 of IP system equipped with a camera. The stereoscopic display system displays one common stereoscopic image in a distributed manner such that the stereoscopic image can be observed from multi directions. Each of the stereoscopic display devices 1 comprises IP stereoscopic image display means 10 formed of image display means 11 for performing stereoscopic display of IP system and a lens array 12, a camera 20, and a computation means 30. Each of the stereoscopic display devices 1 causes the computation means 30 to calculate a coordinate conversion formula for converting a marker coordinate into a
