Patent ID: 7678621

Claim:
A crystallization pattern including amorphous silicon film on a glass substrate, which is crystallized into polycrystalline silicon as a laser is irradiated thereto, the crystallization pattern comprising: at least one of: a hole and a dimple in the amorphous silicon film; a peripheral region located within a first distance from an edge of the crystallization pattern and including a first area of lateral growth; and an internal region located away from the edge of the crystallization pattern by more than the first distance, wherein the internal region is divided into at least one sub-region, each sub-region includes one crystallization inducement pattern, an edge of each sub-region is located within a second distance from the crystallization inducement pattern, and each sub-region includes a second area of lateral growth commencing at the crystallization inducement pattern; wherein the first area of lateral growth and the second area of lateral growth simultaneously exist.
