Abstract
A liquid crystal display device has a pixel electrode substrate with a step defined by adjacent display and non-display areas. The display area has substantially the same height as a portion of the close periphery thereof. In the liquid crystal display device, the step is an electrically insulated dummy part which is not used as the display area. The dummy part has the same layer structure as the pixels in the display area.
