Patent ID: 8416370

Claim:
A liquid crystal display device comprising: an array substrate and a counter substrate facing each other and including a liquid crystal layer interposed between inner surfaces of the array substrate and the counter substrate; a polarizer plate attached to each of respective outer surfaces opposed to the inner surfaces of the counter substrate and the array substrate; an active area formed on the array substrate and the counter substrate to form a plurality of pixels in a matrix; a common voltage supply pad formed at a corner of the array substrate; a common voltage supply region formed on the counter substrate to supply the common voltage to a counter electrode; a conductive element to connect the common voltage supply pad on the array substrate to the counter electrode extending to the common voltage supply region facing the common voltage supply pad; a shield layer formed on the counter substrate to surround the active area and extending to the common voltage supply region facing the common voltage supply pad; and a polarizer plate fiducial mark formed on the counter substrate 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 said shield layer to produce a pattern defined by retained portions of said material of the shield layer and aperture portions where the material of the shield layer has been removed.
