摘要： A semiconductor device such as an RFID, which can easily generate a given stable potential, is provided. Circuits included in a semiconductor device are categorized depending on whether a given stable power source potential is necessary. A power source potential generated from a wireless signal received by an antenna with the use of the antenna and a rectifier circuit is supplied to a circuit which needs a given stable power source potential through a regulator. On the other hand, a power source potential generated by the rectifier circuit is supplied to a circuit other than the circuit which needs the arbitrary power source potential. Thus, a semiconductor device including a regulator circuit easily designed with a smaller layout can be provided, and the semiconductor device can easily generate a given stable power source potential.

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： Image quality of a field-sequential liquid crystal display device is improved by increasing the frequency of input of an image signal. Among pixels arranged in matrix, image signals are concurrently supplied to pixels provided in a plurality of rows. Thus, the frequency of input of an image signal to each of the pixels of the liquid crystal display device can be increased. 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 image quality can be improved.
