Patent ID: 8493543

Claim:
A liquid crystal display device comprising: a first substrate; a second substrate which faces the first substrate; a liquid crystal which is interposed between the first and second substrates, a plurality of scanning lines and signal lines arranged in a matrix shape; a plurality of switching elements arranged in the vicinities of intersections of the scanning lines and the signal lines in a display area; a plurality of pixel electrodes electrically connected to the switching elements; a first plurality of dummy pixels formed in a first non-display area located in the periphery of the display area are formed on the first substrate on at least one of the left side and the right side of a liquid crystal layer in plan view; and a second plurality of dummy pixels formed in a second non-display area located in the periphery of the display area are foamed on the first substrate on at least one of the top side and the bottom side of a liquid crystal layer in plan view, wherein each of the first plurality of dummy pixels is provided with a first plurality of switching elements connected to one of the scanning lines, the first plurality of switching elements are connected to each other in parallel, and one electrode of each of the first plurality of switching elements is connected to a first wiring of a common potential, and wherein each of the second plurality of dummy pixels is provided with a second plurality of switching elements connected to one of the signal lines, the plurality of switching elements are connected to each other in parallel, and one electrode of each of the second plurality of switching elements is connected to a second wiring of the common potential, and wherein each of the first plurality of dummy pixels are larger is size than each of the second plurality of dummy pixels.
