Abstract
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.
