摘要： Etching of a semiconductor layer including a part over a gate wiring and formation of a contact hole for connection between a pixel electrode and a drain electrode are performed by one-time photolithography step and one-time etching step; thus, the number of photolithography steps is reduced. The exposed part of the gate wiring is covered by an insulating layer, and this insulating layer also functions as a spacer for maintaining a space for a liquid crystal layer. By the reduction in the number of photolithography steps, a liquid crystal display device can be provided at lower cost and higher productivity. Using an oxide semiconductor for the semiconductor layer can realize a liquid crystal display device with low power consumption and high reliability.

摘要： A PLL circuit includes a phase detector, a loop filter (LF), a voltage-controlled oscillator (VCO), and a frequency divider. The phase detector compares a phase of a signal Fs which is input from outside with a phase of a signal Fo/N which is input from the frequency divider. The loop filter generates a signal Vin by removing alternating current components from a signal input from the phase detector. The voltage-controlled oscillator outputs a signal Fo based on the signal Vin input from the loop filter. The frequency divider converts the signal Fo output from the voltage-controlled oscillator into Fo/N (frequency division by N), and outputs it to the phase detector.

摘要： An object of the invention is to suppress degradation in image quality of a liquid crystal display device which performs display by field sequential method and to reduce power consumption of a backlight. The highest brightness of a first color light in a pixel region is detected. Gamma correction is performed so that transmittance of a pixel of the region displaying the highest brightness of the first color light is set to maximum and transmittance of other pixel of the region is decreased in accordance with lowering of the first color light intensity, and the region is irradiated with the highest brightness of the first color light. Similarly, a second color light is irradiated in another region concurrently with irradiation of the first color, whereby input of an image signal and lighting of the backlight are performed simultaneously in every region of the pixel portion.
