Just under an opening of the black matrix, a second pixel electrode exists on the uppermost layer of a TFT substrate. The second pixel electrode is formed on the gate insulating film and the interlayer insulating film except a contact part. An area where the second pixel electrode exists on the uppermost layer of the TFT substrate is a main area. By a combination structure of the first pixel electrode and the second pixel electrode, the transmittance of the liquid crystal layer in the end area is made relatively higher than the transmittance in the main area.
