The screen comprises support components (2,3) which are erected and spaced apart, in a usage position, in order to hold the sheet or panel (6) fixed to them in the upright position. The screen has a support device (4) for each support component. A base plate (15,15') holds apart at least two support devices at a specific distance from each other. The support components are maintained apart by the usage distance. The base plate is provided with a least two duly spaced apart holes (16,16',17,17').
