Abstract
A laser annealing device includes a laser generator, a beam splitter, a λ/2 phase difference member, a first reflective member, and a second reflective member. The laser generator emits a laser beam. The beam splitter splits the laser beam into a first reflective light and a transmissive light. The λ/2 phase difference member changes a polarization component of the transmissive light. The first reflective member reflects the transmissive light having the changed polarization component. The second reflective member reflects the transmissive light having the changed polarization component in a way such that the transmissive light having the changed polarization component which is reflected from the first reflective member is incident to the beam splitter.
