A laser beam irradiation apparatus includes a laser light source, a controller for controlling energy of light generated by the laser source, a first optical system for adjusting a shape of light that has passed through the controller, a scanner for adjusting the direction of light that has passed through the first optical system, and an F-theta lens for reducing a beam that has passed through the scanner.

Laser beam irradiation apparatus

Laser beam irradiation apparatus and manufacturing method of organic light emitting display apparatus using the same

Apparatus for uniformizing light amount distribution by shaking line beams along a longitudinal axis direction is provided. The apparatus includes a mirror mount, a mirror, an actuator, and a deformation member. The mirror fixed to the mirror mount and includes a reflective surface. The actuator is disposed at a distance from the mirror mount and configured to repeat expansion and contraction along a first direction. The deformation member includes a plurality of blocks connected to each other by flexible joints and is coupled to the actuator and the mirror mount. The deformation member is configured to change a displacement in the first direction due to operation of the actuator to a displacement in a second direction that crosses the first direction, amplify the changed displacement, and transmit the amplified displacement to the mirror mount.
