ALIGN MARK FORMED ON DISPLAY PANEL OF STEREOSCOPIC IMAGE DISPLAY, ALIGNING METHOD AND SYSTEM USING THE ALIGN MARK

摘要

PURPOSE: An align mark formed on a display panel of a 3D image display device, an align method using the same, and a system thereof are provided to accurately align a pattern retarder and the display panel without separately forming an align mark on the pattern retarder. CONSTITUTION: A left pattern and a right pattern are formed on align marks(AK1~AK6) which are formed on a right side and a left side of a display panel(PNL). The right and left patterns are aligned on a central boundary line of a pattern retarder(FPR). The pattern retarder includes first and second polarization selection patterns. The central boundary line of the pattern retarder includes a central boundary line between the first and second polarization selection patterns.
