Provided is a two-axis scanner. The two-axis scanner includes: a base; a stage disposed on the base; and a stage actuator that is disposed between the base and the stage and moves the stage along two axes. The stage actuator includes: a first stationary part having a predetermined shape; a horizontally movable frame surrounding the first stationary part, wherein a first horizontal deformable torsion spring is disposed between the first stationary part and the horizontally movable frame; a horizontal driver actuating the horizontally movable frame in a horizontal scanning direction; an auxiliary frame surrounding the horizontally movable frame, wherein a first vertical deformable torsion spring is disposed between the horizontally movable frame and the auxiliary frame; a vertically movable frame surrounding the auxiliary frame, wherein a second horizontal deformable torsion spring is disposed between the auxiliary frame and the vertically movable frame; a second stationary part at both sides of the vertically movable frame in a first direction, wherein a second vertical deformable torsion spring is disposed between the vertically movable frame and the second stationary part; and a vertical driver vertically actuating the vertically movable frame. The stage is disposed on the auxiliary frame.
