Abstract: An object is to provide a moving object structure capable of reducing power loss caused when power is supplied from a power feeding device to a moving object by wireless communication. Another object is to provide a moving object structure capable of reducing the intensity of radio waves radiated to the surroundings. A moving object having a plurality of antennas receives radio waves transmitted from a power feeding device. At least one of the plurality of antennas is installed apart from the other antenna(s) of the moving object. Then, the radio waves transmitted from the power feeding device are received by all the plurality of antennas and converted into electric energy. Alternatively, the radio waves transmitted from the power feeding device are received by one or more selected from the plurality of antennas and converted into electric energy.

Abstract: The sizes of an evaporation mask used for a full-color light-emitting device and an evaporation mask used for a lighting device are different from each other. For this reason, separate evaporation masks are necessary, and in the case of processing a large number of substrates at once, many evaporation masks are prepared in accordance with the number of substrates to be processed, thereby increasing the total footprint of a manufacturing apparatus. One object of the present invention is to solve a problem of such an increase. A full-color display device can be manufactured by using a color filter and white light-emitting elements in combination. By this manner, a manufacturing line for the light-emitting device can have some steps in common with a manufacturing line for the lighting device; consequently, the total footprint of the manufacturing apparatus is reduced.

Abstract: An object is to reduce power consumption of a display device and to suppress deterioration of display quality. As a transistor provided for each pixel, a transistor including an oxide semiconductor layer is used. Note that off-state current of the transistor can be decreased when the oxide semiconductor layer is highly purified. Therefore, variation in the value of a data signal due to the off-state current of the transistor can be suppressed. That is, display deterioration (change) which occurs when writing frequency of the data signal to the pixel including the transistor is reduced (when a break period is lengthened) can be suppressed. In addition, flickers in display which generates when the frequency of an alternating-current driving signal supplied to a signal line in the break period is reduced can be suppressed.

Abstract: An oxide semiconductor film with excellent crystallinity is formed. At the time when an oxide semiconductor film is formed, as a substrate is heated to a temperature of higher than or equal to a first temperature and lower than a second temperature, a part of the substrate having a typical length of 1 nm to 1 μm is heated to a temperature higher than or equal to the second temperature. Here, the first temperature means a temperature at which crystallization occurs with some stimulation, and the second temperature means a temperature at which crystallization occurs spontaneously without any stimulation. Further, the typical length is defined as the square root of a value obtained in such a manner that the area of the part is divided by the circular constant.

Abstract: An object is to provide a liquid crystal display device which can recognize image display even when the liquid crystal display device is used in a dim environment. In one pixel, a pixel electrode including both of a region where incident light through a liquid crystal layer is reflected and a transmissive region is provided, and image display can be performed in both modes: the reflective mode where external light is used as an illumination light source; and the transmissive mode where the backlight is used as an illumination light source. When there is external light with insufficient brightness, that is, in a dim environment, the backlight emits weak light and an image is displayed in the reflective mode, whereby image display can be performed.
