Abstract: A protective film peeling apparatus includes a peeling tape, a tape support portion disposed under one side of the peeling tape, a first pressing portion which is disposed on the one side of the peeling and fixes the one side of the peeling tape to the tape support portion, a second pressing portion which is disposed on another side of the peeling tape and presses and attaches the another side of the peeling tape to one side of a dummy portion of a protective film on a panel, and a grip portion disposed on the dummy portion. The tape support portion and the first pressing portion peel the one side of the dummy portion and a predetermined portion of the dummy portion, and the grip portion peel a remaining portion of the dummy portion.

Abstract: A laser apparatus may include a laser generator generating at least one a laser beam, which is used as an input light, an optical system converting the input light, which is provided from the laser generator, into a plurality of pattern lights, and a stage, on which a target object is loaded. The output light may be irradiated onto the target object. The optical system may divide the input light into a plurality of divided lights, and the pattern lights may be produced by constructive interference of the plurality of divided lights. A diameter of each of the pattern lights may be smaller than a diameter of the input light.
