Many psychoanalytic theories address the question of the space of play. Based on Freud, the author first of all tries to show that the originality of psychoanalysis lets us consider the space of play as a scene (Bühne) which opens onto the Other Scene, the unconscious. A structural analogy between play space and tragic scene will be considered. Next the author will study the Winnicottian invention of potential space which allows us to explain the experience of play from a psychogenetic point of view. In this perspective it will be important to locate the area in which play takes place, an area of illusion that Winnicott describes as paradoxical. Finally a third perspective considering how play constitutes its own symbolical space will be considered. The author will propose that play institutes a third space allowing something to be said and at the same time a subjective division.
