The invention relates to a roller shutter made of individual slats which are arranged on the front side of at least one transversal groove. The grooves open in a diagonal manner in an upward direction. Said groove prevents sunlight from crossing the light slots and being reflected on the lower side of the upper slats. Sunlight would form a very bright glare on the rear side of the roller shutter without said groove, whereby said glare would otherwise extend over the vertical length of the roller shutter. |
