Abstract
A liquid crystal display element having a liquid crystal cell formed by bonding a pair of transparent substrates, and a polarizing plate disposed at least outside of the transparent substrate of display surface comprising a Cr.sub.2 O.sub.3 thin film formed 300 to 1000 Angstroms thick on the outer surface of the transparent substrate of the display surface. Thus, the liquid crystal display element can effectively prevent a dazzlement due to the reflection of an external light on the surface of a transparent substrate of display surface side.
