Abstract:
Disclosed is an optical sheet which is used in a liquid crystal display. The optical sheet is not readily damaged by external impact, and thus is easy to handle and can reduce failure rate, leading to a decrease in production cost and an increase in production efficiency. Also, it can prevent a decrease in brightness.
