Provided is a method of forming a single crystal silicon thin film using an SLS method and a patterned grain boundary filtering region. The method of forming a single crystal silicon thin film by crystallizing an amorphous silicon layer deposited on a substrate, includes patterning the amorphous silicon layer to have a second region having a narrower width than the first and third regions to prevent grain boundaries from reaching the third region, wherein the second region connects a first region where the crystallization commences and the third region where a single crystal without beam boundaries can grow, partially forming a mask layer on the first region, and crystallizing the amorphous silicon layer by irradiating a laser beam from the first region to the third region in steps using a linear beam SLS method.
