14 Abstract: "Projection screen". A projection screen is described which comprises a single plate of a transparent material. The diffusion in the horizontal direction is provided by filamentary particles which are oriented sub- stantially in one direction in the plate material. Both surfaces of the plate are then capable of performing different functions, yielding a projection screen with an optimally uniform brightness distribution, minimal colour faults and maximum contrast.
