An objective of the present invention is to provide a multifunctional dual roll blind with a roll screen and a roll screen used for the same which are divided into an upper portion and a lower portion to shade an entire screen from light or open and adjust only the upper portion while selectively shading only the lower portion from light, and partially open the upper portion and the lower portion at the same time to satisfy user needs. According to the present invention, the roll screen comprises: a first adjustment unit formed on a starting portion; a third adjustment unit which corresponds to the first adjustment unit and is formed on an ending portion; and a second adjustment unit formed between the first and the second adjustment unit. First net portions through which an object on an opposite side thereof is seen and first shading portions through which an object on an opposite side thereof is not seen are alternately and repeatedly formed on a prescribed section of the first adjustment unit in a prescribed width. Third net portions corresponding to the first net portions, through which an object on an opposite side thereof is seen and third shading portions corresponding to the first shading portions, through which an object on an opposite side thereof is not seen are alternately and repeatedly formed on a prescribed section of the third adjustment unit in a prescribed width. Second net portions corresponding to the first and the third net portions, through which an object on an opposite side thereof is seen and second shading portions through which an object on an opposite side thereof is not seen are alternately and repeatedly formed on a prescribed section of the second adjustment unit. The widths of the second shading portions are at least two times wider than the widths of the first and the third shading portions. |
