To prevent the deterioration of a liquid crystal material and to embody a good display grade over the entire part of a liquid crystal display element by adding a UV absorptive material to the liquid crystal material adjacent near the sealing material for sealing liquid crystals formed by using a UV curing resin at the time of assembling the liquid crystal display element, such as a liquid crystal display panel.
This liquid crystal display element has the liquid crystal display panel constitution formed by adding a UV absorbent to the liquid crystals of part of the panel at the time of assembling the liquid crystal panel. A benzotriazole based UV absorbent or cyanoacrylate based UV absorbent is used as the UV absorbent. The amt. of the UV absorbent to be added to the liquid crystal material (32) adjacent near the sealing material for sealing liquid crystals is specified to 0.5 to 1.5wt.%. The unevenness in the threshold voltage drop which heretofore occurs in the display area near the liquid crystal sealing part for which the UV curing resin is used or the sealing part of the injection port is eliminated.
