摘要： A semiconductor device with high definition, which includes a plurality of sets each including a photosensor and a display element including a light-emitting element arranged in a matrix is provided, wherein a power supply line electrically connected to the display element also serves as a power supply line electrically connected to the photosensor. Thus, the semiconductor device with high definition can be provided without decreasing the width of each power supply line. Thus, the definition of the semiconductor device can be improved while securing the stability of the potential of the power supply line. The stability of the potential of the power supply line leads to the stability of the driving voltage of the display element and the stability of the driving voltage of the photosensor. Accordingly, the semiconductor device with high definition, high display quality, and high accuracy of imaging or detection of an object can be provided.

摘要： In a field-sequential liquid crystal display device, image quality and detection accuracy in image capture are improved by increasing the frequency of input of image signals and securing a sufficient imaging period. Image signals are concurrently supplied to pixels provided in a plurality of rows among pixels arranged in matrix. Further, image capture is concurrently performed in pixels provided in a plurality of rows among pixels arranged in matrix. Thus, the frequency of input of an image signal to each pixel of the liquid crystal display device can be increased and a sufficient imaging period can be secured. As a result, in the liquid crystal display device, display deterioration such as color break which is caused in a field-sequential liquid crystal display device can be suppressed and improvements in image quality and detection accuracy in image capture can be realized.

摘要： To improve field effect mobility of an inverted-staggered TFT using amorphous silicon. In an inverted-staggered TFT, a thin amorphous semiconductor layer which is made to have n-type conductivity is formed between a gate insulating film and an amorphous semiconductor layer. By depositing an amorphous semiconductor layer after a substrate over which up to a gate insulating film is formed is exposed to an atmosphere which contains a phosphine gas in a small amount, an amorphous semiconductor layer which contains phosphorus is formed during the early stage of deposition of the amorphous semiconductor layer. The thus obtained amorphous semiconductor layer has the concentration peak of phosphorus around the surface of the gate insulating film.
