ABSTRACT:
A liquid crystal display device has a semiconductor substrate. A plurality of switching elements are arranged on the substrate in matrix, and a plurality of pixel electrodes are provided above the switching elements, arranged in matrix corresponding to the switching elements. A liquid crystal layer is provided on the pixel electrodes. The switching element is connected with a corresponding pixel electrode by a wiring layer. Dummy layers are provided in the same level as the wiring layer so that a surface of the dummy layer is substantially flush with a surface of the wiring layer.
