METHOD OF MANUFACTURING DISPLAY DEVICE

摘要

A method for manufacturing an LCD(Liquid Crystal Display) is provided to improve the electrical characteristics and reliability of a flexible display device by preventing multilayered thin films from being misaligned according to the retraction of an existing plastic substrate. A sacrifice pattern is formed on an auxiliary substrate. In this case, a sacrifice layer is first formed on the auxiliary substrate. Then the peripheral area of the auxiliary substrate is exposed through photolithography for the sacrifice layer. A reserve flexible substrate is formed on the auxiliary substrate and the sacrifice pattern. A certain thin film structure is formed on the reserve flexible substrate. A passivation film is formed on the thin film structure. Holes to expose the sacrifice pattern are formed at the reserve flexible substrate. The sacrifice pattern is etched through the exposed holes. The passivation film is removed. The reserve flexible substrate is separated from the auxiliary substrate.
