A shutter simulation Venetian blind is constructed to include a fixed headrail shield by a top block at the top side of the window, two side blocks longitudinally located on two sides of the window, a bottom rail suspended below the headrail, a set of slats arranged in parallel between the headrail and the bottom rail, two ladder tapes, a tilting control mechanism, and a lift lock adapted to lock the bottom rail at a desired elevation. Each side block has a front shielding wall. The ladder tapes are connected in parallel at two sides between the headrail and the bottom rail and respectively linked to the ends of the slats behind the front shielding walls of the side blocks. The tilting control mechanism is formed of an operating rod and a tilt rod for driving the ladder tapes to control the tilting angle of the slats.
