Abstract

Disclosed is an optical sheet for use in liquid crystal displays, which is not easily damaged by external impact, thus facilitating handling thereof and decreasing defective rates, resulting in reduced production costs and increased production efficiency. Decreases in the luminance of the optical sheet due to damage can be prevented.
