ABSTRACT:
A liquid crystal display apparatus has LOCOS insulating layers having an increased thickness under pixel electrodes, the LOCOS insulating layers being formed by LOCOS-oxidizing a Si layer formed on a glass substrate. Because of the thick LOCOS insulating layers, the pixel electrodes are provided at an elevated position which is substantially the same level as the top surfaces of the TFT portions. The apparatus also has metal layers of W, Al or the like which connect the elevated pixel electrodes and the drains. After W, Al or the like is deposited on the top surface of the drains, ITO deposited to form the pixel electrodes so that the electrodes are connected to the deposited metal layers.
