摘要：
An object is to provide an active matrix liquid crystal display device in which plural kinds of circuits are formed over one substrate and plural kinds of thin film transistors are provided corresponding to characteristics of the plural kinds of circuits. An inverted-coplanar thin film transistor including an oxide semiconductor layer which is over and overlaps with a source electrode layer and a drain electrode layer is used for a pixel thin film transistor. A channel-protective thin film transistor is used for a driver-circuit thin film transistor is used. In addition, main parts of the pixel thin film transistor are formed using a light-transmitting material, so that the aperture ratio is increased.
