Abstract: A liquid crystal display device includes first and second substrates. The first substrate includes a pixel electrode having a main pixel electrode in the shape of a belt and a first alignment film covering the pixel electrode. The first alignment film is alignment processed in a first alignment treatment direction substantially in parallel with an extending direction of the main pixel electrode. The second substrate includes a common electrode arranged on both sides sandwiching the pixel electrode and extending substantially in parallel with the extending direction of the main pixel electrode. A sub-common electrode extends in a direction crossing the extending direction of the main pixel electrode on one end side of the main pixel electrode located on a starting side of the first alignment treatment direction. A second alignment film is alignment processed in a second alignment treatment direction substantially in the same direction as the first alignment treatment direction.
