DISPLAY APPARATUS AND METHOD OF MANUFACTURING THEREOF

Abstract

A liquid crystal display (LCD) apparatus and a method of manufacturing the same include a seal line having two protrusions, one of the protrusions having a liquid crystal (LC) injection hole. Moreover, the LCD apparatus having the seal line constitutes a closed loop. The display apparatus and the manufacturing method thereof increase production yields because the number of apparatus substrates for the display apparatus obtained from a mother substrate is increased by minimizing a distance between two adjacent apparatus substrates on the mother substrate. The method of manufacturing an exemplary LCD apparatus includes a one drop filling method or a vacuum injection method.
