Abstract: A liquid crystal display (LCD) includes thin film transistors (TFTs) each having spaced apart source/drain electrodes and an oxide-type semiconductive film disposed over and between the source/drain electrodes to define an active layer. Each of the source/drain electrodes includes a portion of a subdivided transparent conductive layer where one subdivision of the transparent conductive layer continues from within its one of the source/drain electrodes to define an optically exposed pixel-electrode that is reliably connected integrally to the one source/drain electrode. Mass production costs can be reduced and production reliability increased because a fewer number of photolithographic masks can be used to form the TFTs.
