摘要： A test circuit and a test method using a plurality of oscillation circuits for evaluation are provided in order to reduce the measuring time and simplify the test. One measuring terminal is shared by a plurality of oscillation circuits for evaluation that are formed over the same substrate as a semiconductor device such as a display device, and the plurality of oscillation circuits for evaluation can be tested by the measuring output terminal. Then, the measurement results are Fourier transformed to obtain the oscillation frequency of the plurality of oscillation circuits for evaluation at the same time. Thus, variations in semiconductor elements can be evaluated.

摘要： In a case where an ASK method is used for a communication method between a semiconductor device and a reader/writer, the amplitude of a radio signal is changed by data transmitted from the semiconductor device to the reader/writer when data is not transmitted from the reader/writer to the semiconductor device. Therefore, in some cases, the semiconductor device mistakes data transmitted from the semiconductor device itself for data transmitted from the reader/writer to the semiconductor device. The semiconductor device includes an antenna circuit, a transmission circuit, a reception circuit, and an arithmetic processing circuit. The antenna circuit transmits and receives a radio signal. The transmission circuit outputs to the reception circuit a signal showing whether or not the antenna circuit is transmitting the radio signal.

摘要： An object is to provide a display device which has high visibility and has a touch recognition function with a high degree of accuracy, by combining a liquid crystal layer where liquid crystals are dispersed in a polymer and a light emitting element. In a display device using a liquid crystal layer where liquid crystals are dispersed in a polymer, a light-transmitting spacer is provided so as to overlap with a light receiving element which has a touch recognition function. The light-transmitting spacer can prevent light incident on the light receiving element from being dispersed by the liquid crystals, while maintaining a cell gap in the liquid crystal layer, and thus achieve a touch recognition function with a high degree of accuracy with high visibility.
