(57) ABSTRACT
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 substrate 11 and a second substrate 12 which 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 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 16 for 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 hole 15 into a plurality of portions by using the same material as the post structures.
