摘要： To provide a display device with a novel structure that can achieve both thickness reduction and favorable display quality. In a structure of a display device including a liquid crystal layer between a pixel electrode and a counter electrode, a common electrode and an electrode of a capacitor in a touch sensor on the counter electrode side are formed integrally and supplied with a pulse signal. On the element substrate side, a signal to be supplied to a capacitor line that forms a capacitance with the pixel electrode is in conjunction with the pulse signal so as to cancel a change in an electric field applied to the liquid crystal layer. Such a structure can achieve a display device with a touch sensor function that can cancel a change in an electric field applied to a liquid crystal layer even when the electric field is changed by a pulse signal.

摘要： It is an object to provide a liquid crystal display device and a driving method of a liquid crystal display device in each of which deterioration of an image display function can be suppressed and power consumption can be sufficiently reduced. In the liquid crystal display device, a fixed potential is input to a capacitor before a power source is turned off, so that a potential difference between electrodes of the capacitor disappears (capacitance becomes almost zero) such that electric field is not applied to liquid crystals, whereby the liquid crystals are in an initial state. When the supply of the power source is stopped after an initial-state image is displayed, unnecessary electric field is not continuously applied to the liquid crystals in an off state, whereby the liquid crystals can be in the stable initial state; therefore, the liquid crystals can be prevented from deteriorating.
摘要翻译：本发明的目的是提供一种能够抑制图像显示功能的劣化并且能够充分降低功耗的液晶显示装置的液晶显示装置和驱动方法。在液晶显示装置中，在电源关闭之前将固定电位输入到电容器，使得电容器的电极之间的电位差消失（电容变为几乎为零），使得电场不施加于液晶，由此液晶处于初始状态。当在显示初始状态图像之后停止电源的供给时，在关闭状态下不会对液晶持续施加不必要的电场，从而液晶可以处于稳定的初始状态; 因此，可以防止液晶的劣化。

The first electrode is a metal oxide film in contact with an inorganic insulating film over the transistor.

摘要： Provided is a light-emitting device which can prevent appearance of an after-image after power on. Before or after supply of a power voltage applied to a light-emitting element is cut, a potential of a gate electrode of a transistor controlling the supply of the power voltage to the light-emitting element is initialized. Specifically, in the case where the transistor is n-channel type, the potential of the gate electrode is initialized so that a gate voltage is equal to or lower than a threshold voltage. In the case where the transistor is p-channel type, the potential of the gate electrode is initialized so that the gate voltage is equal to or higher than the threshold voltage.
