  • Patent number: 8054438
    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.

  • Patent number: 7446826
    Abstract: A display panel includes a first substrate, a second substrate, a connecting member and a strength-reinforcing member. The second substrate faces the first substrate, and includes a display area and a peripheral area surrounding the display area. The connecting member is disposed in the peripheral area to electrically connect the first substrate and the second substrate. The strength-reinforcing member protrudes from the second substrate and is disposed inside the connecting member. Thus, the strength-reinforcing member increases strength of the connecting member and stabilizes electrical connection between the first and second substrates, thereby improving display quality of a display device having the display panel.
