摘要： It is an object to provide a display device in which a problem of light leakage from a liquid crystal element in black display is reduced or overcome and the contrast is improved. It is another object to provide a pixel circuit having a function to control a lighting state of a backlight based on each pixel. These objects are achieved by turning off a light-emitting element in display of a black gray scale, and by providing a light-emitting element in each pixel and providing, in a pixel circuit, a function to individually control lighting and non-lighting of the light-emitting element depending on a gray scale to perform display. When a backlight is provided in each pixel, a light-emitting element that is a backlight is turned off when a black gray scale is displayed, whereby reduction in contrast due to light leakage from a liquid crystal element can be prevented.

摘要： A transistor whose channel region includes an oxide semiconductor is used as a pull down transistor. The band gap of the oxide semiconductor is 2.0 eV or more, preferably 2.5 eV or more, more preferably 3.0 eV or more. Thus, hot carrier degradation in the transistor can be suppressed. Accordingly, the circuit size of the semiconductor device including the pull down transistor can be made small. Further, a gate of a pull up transistor is made to be in a floating state by switching of on/off of the transistor whose channel region includes an oxide semiconductor. Note that when the oxide semiconductor is highly purified, the off-state current of the transistor can be 1 aA/μm (1×10−18 A/μm) or less. Therefore, the drive capability of the semiconductor device can be improved.

摘要： It is an object to provide a display module which can display a correct gray scale by a field sequential driving method and an electronic device including the display module. One frame period is divided into a plurality of lighting periods, and in each of the plurality of lighting periods, signals are supplied to a pixel a plurality of times, whereby the transmissivity of a liquid crystal element is changed over time. Accordingly, even with the use of a liquid crystal element with low response speed as a display element, a correct gray scale can be expressed. In addition, the transmissivity of the liquid crystal element is set at 0% or a backlight is controlled not to emit light in switching of lighting of a backlight or switching of lighting periods, whereby a more correct gray scale can be expressed.

摘要： With an offset circuit including transistors of the same conductivity type, offset of an input signal is performed. Then, the input signal after the offset is supplied to a logic circuit including transistors of the same conductivity type as that of the offset circuit, thereby H and L levels of the input signal can be shifted at the same time. Further, since the offset circuit and the logic circuit are formed using the transistors of the same conductivity type, a display device can be manufactured at a low cost.

摘要： A semiconductor device where delay or distortion of a signal output to a gate signal line in a selection period is reduced is provided. The semiconductor device includes a gate signal line, a first and second gate driver circuits which output a selection signal and a non-selection signal to the gate signal line, and pixels electrically connected to the gate signal line and supplied with the two signals. In a period during which the gate signal line is selected, both the first and second gate driver circuits output the selection signal to the gate signal line. In a period during which the gate signal line is not selected, one of the first and second gate driver circuits outputs the non-selection signal to the gate signal line, and the other gate driver circuit outputs neither the selection signal nor the non-selection signal to the gate signal line.
