## Background
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a window covering and, more particularly, to a cordless magnetically attractive shade assembly.
2. Description of the Related Art
A conventional roman shade comprises a headrail, a shading member mounted on and extended from the headrail, a plurality of transverse rods mounted on the shading member, and a lift cord extended through the shading member and secured to the bottom of the shading member to move the shading member upward and downward. When the lift cord is pulled, the transverse rods are driven and moved to roll or expand the shading member. Thus, the bottom of the shading member is lifted and folded by the lift cord to allow passage of the solar rays and is lowered and expanded by the lift cord to provide a shading effect. However, the lift cord depends from a side of the roman shade so that the lift cord is easily tangled with a child's neck during playing, thereby causing danger to the child. In addition, when the shading member is fully expanded, the solar rays cannot penetrate the shading member so that the indoor light is too weak, and when the shading member is fully folded, the solar rays directly irradiate the indoor room so that the indoor light is too strong.
