Each ITO electrode and an alignment layer laminated to the inside of the lower surface glass substrate, a spacer disposed between the inside of the glass substrate, the liquid crystal injected into the liquid crystal cell, and a polarizing plate and a phase difference film attached to the outer surface of the glass body. A liquid crystal display device comprising: a viewing angle magnification layer capable of increasing the viewing angle of the liquid crystal display device and improving visibility between the upper surface glass substrate and the polarizing plate corresponding thereto, thereby providing a viewing angle for a display image. The present invention relates to an LCD manufacturing apparatus and a method of manufacturing the same, which are capable of producing products having excellent display quality by expanding and improving the visibility of LCD.
