A liquid crystal display having an injection hole post structures compatible with liquid crystal are formed in an area near an injection hole to prevent pollutants seeped from an end-sealing material from penetrating into a display area, thereby suppressing the occurrence of picture quality trouble which easily occurs in the display area. The liquid crystal display includes a first substrateand a second substratewhich are disposed with a predetermined gap therebetween, in which liquid crystal is sealed in the gap. The liquid crystal display further includes: post structures for controlling the gap; a sealing material provided outside the display for sealing the liquid crystal in the gap, and forming the open injection hole for injecting the liquid crystal therethrough; the end-sealing materialfor sealing the injection hole after the liquid crystal is sealed in; and injection hole post structures provided in the area near the injection hole, for dividing the injection holeinto a plurality of portions by using the same material as the post structures.

Liquid crystal display and method for manufacturing liquid crystal display

A liquid crystal display comprises an injection hole post structures compatible with liquid crystal formed in an area near an injection hole to prevent pollutants seeped from an end-sealing material from penetrating into a display area, thereby suppressing the deterioration of picture quality in the display area. The liquid crystal display comprises a first substrate and a second substrate having a predetermined gap therebetween. Liquid crystal is sealed in the gap. The liquid crystal display comprises post structures for controlling the gap, and a sealing material provided outside the display area for sealing the liquid crystal in the gap, and forming the open injection hole for injecting the liquid crystal therethrough. The end-sealing material seals the injection hole after the liquid crystal is sealed. Injection hole post structures are provided in the area near the injection hole, for dividing the injection hole into a plurality of portions.

The present invention provides a liquid crystal display device having a narrow frame, which is capable of effectively removing a defective display owing to entering of a seal member to a display area. More specifically, the present invention is directed to a liquid crystal display device comprising first and second substratesanddisposed at a predetermined gap d; a liquid crystal sealed in the gap d; a seal memberprovided at the gap dbetween the first and second substratesandand outside a display area, the seal memberbeing for sealing the liquid crystal; and a wall-like structureprovided outside the display areaand inside the seal member, the wall-like structurebeing made of a material different from that of the seal memberand composed of a plurality of rows.

Liquid crystal display device and method of fabricating the same

To prevent the damage of a display device by static electricity and to drive the display device with low voltage, on a transparent substrate of a liquid crystal display, two short circuit wires are provided, connected via a resistance. Each of the data lines is connected to the one short circuit wire via a first switching circuit, whereas each of the gate lines is connected to the other short circuit wire via a second switching circuit. A switching circuit is turned on when the potential difference between a data line and the one short circuit wire or the potential difference between a gate line and the second short circuit wire exceeds a predetermined value. When images are displayed on a liquid crystal display, the average voltage applied to each of data lines is applied to the first short circuit wire and the average voltage of voltages applied to each gate line is applied to the second short circuit wire to turn on the switching circuits.
