  • 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.

    Abstract: A display panel includes an array substrate, an opposite substrate facing the array substrate, and a liquid crystal layer interposed between the array and opposite substrates. The array substrate includes a gate wiring, a data wiring, a pixel section, a sensor wiring section, a sensor electrode section and a sensor pad section. The gate wiring is formed in a first direction. The data wiring is formed in a second direction crossing the first direction. The pixel section is electrically connected to the gate and data wirings. The sensor wiring section is spaced apart from the gate and data wirings. The sensor electrode section is electrically connected to the sensor wiring section. The sensor pad section applies a test voltage to the sensor wiring section in order to inspect a display panel defect. Therefore, a short defect, which is generated between the array substrate and the opposite substrate, may be easily inspected.
