The present invention relates to a blind. According to an embodiment of the present invention, a blind comprises: multiple slats having predefined length and width; and a pair of guide rails in which guide slots are disposed from the top to the bottom so as to be spaced apart from each other in a horizontal direction to guide the lifting and rotation of the slat. Screw parts comprising a screw thread in a helical shape are separately provided on the outer circumferential face of a rotation axis provided at both longitudinal ends of the slat. In the guide slots, a guide protrusion part formed from the top to the bottom in a form assembled with the screw parts is provided. When the slat moves upward and downward, the screw parts slide up and down along the guide protrusion part and when the slat rotates around the rotation axis, the screw part is in a helical motion with respect to the guide protrusion part. |
