An apparatus for displaying still and moving images on a three-dimensional projection screen includes a gas-inflatable envelope made of flexible material with an inner surface serving as three-dimensional projection screen, a gas inlet opening, a fan connected to the gas inlet opening and which generates a gas flow that inflates the envelope, an interior surrounded by the envelope, a projector emitting a projector beam and a reflection mirror set up in the zenith of the envelope, said reflection mirror having a curved mirror surface for deflecting the projector beam onto the inner surface of the envelope. The image generated by the projector beam is visible on the outer surface of the envelope. The projector is configured within the interior of the envelope and aligned in such a way that the projector beam is reflected onto the inner surface serving as a three-dimensional projection screen via the reflection mirror.
