A structure of a roller blind is primarily composed of a cloth which contains light-pervious sides and opaque sides aligned in an equal spacing, and on which is printed with various patterns. After continuously bending the cloth vertically and horizontally, the light-pervious sides of the vertical part are attached to two transparent cloths to constitute a roller blind. When the transparent cloths are suspended evenly, the horizontal part of cloth is in a horizontal shape, so as to enable light to penetrate from each transparent cloth and the vertical part of cloth. On the other hand, when one of the transparent cloths is pulled up, the horizontal part will be tilted, so as to constitute an effect of shading. In addition, a sense of beauty of the blind will be increased by the printed patterns.
