Abstract: A liquid crystal display device includes a substrate including a display area in which display pixels are arranged in a row direction and a column direction, a first dummy area, which is adjacent to a first side, in the row direction, of the display area, and a second dummy area, which is adjacent to a second side, in the row direction, of the display area, pixel electrodes on the substrate, the pixel electrodes including display pixel electrodes, which are respectively disposed in the display pixels, first dummy pixel electrodes, which are disposed in the first dummy area in the column direction, and second dummy pixel electrodes, which are disposed in the second dummy area in the column direction, and an alignment layer disposed on the pixel electrodes, where an average thickness of the alignment layer is larger in the first and second dummy areas than in the display area.
