Abstract
A liquid crystal display device includes a polarizer plate attached to at least one of outer surfaces opposed to the inner surfaces of a counter substrate and an array substrate between which a liquid crystal layer is interposed. Active areas are formed on the respective array and counter substrates to form a pixel matrix. A shield element surrounds the active area on the counter substrate and extends to a corner portion of the counter substrate where a polarizer plate fiducial mark is formed to check alignment error of the polarizer plate attached to each of the respective outer surfaces of the array substrate and the counter substrate, the fiducial mark formed by patterning of the material of the shield layer to produce a pattern defined by retained portions of the material of the shield layer and aperture portions where the material of the shield layer has been removed.
