PURPOSE: A door with a superior utilization ratio is provided to enable a user to easily open and close a door with less power by preventing the collision and interference of doors in an opening and closing process. CONSTITUTION: A door with a superior utilization ratio comprises a incised section(120), a handle(130) and a blocking membrane(140). The incised section is formed by vertically cutting one part of a door in a horizontal direction. The handle is attached to the incised section in a horizontal direction. The blocking membrane can be open and close at the front and rear side of the incised section. The incised section prevents the exposing of a handle to outside.
