Abstract: A highly reliable display device. A first flexible substrate and a second flexible substrate overlap each other with a display element positioned therebetween. Side surfaces of at least one of the first substrate and the second substrate which overlap each other are covered with a high molecular material having a light-transmitting property. The high molecular material is more flexible than the first substrate and the second substrate.

Abstract: A semiconductor device is provided in which power consumption is reduced and an increase in circuit area is inhibited. The semiconductor device includes a high frequency amplifier circuit, an envelope detection circuit, and a power supply circuit. The power supply circuit has a function of supplying a power supply potential to the high frequency amplifier circuit, an output of the high frequency amplifier circuit is connected to the envelope detection circuit, and an output of the envelope detection circuit is connected to the power supply circuit. The power supply circuit can reduce the power consumption by changing the power supply potential in accordance with the output of the high frequency amplifier circuit. The use of an OS transistor in the envelope detection circuit can inhibit an increase in circuit area.

Abstract: A display device that can display an image along a curved surface is provided. In the display device, a first display panel and a second display panel overlap each other with a light-transmitting layer provided therebetween. The light-transmitting layer is positioned on a display surface side of the first display panel, and on a side opposite to the display surface of the second display panel. The light-transmitting layer has an average transmittance of 80% or more with respect to light in the wavelength range of 450 nm to 700 nm and a refractive index higher than that of air. A display region of the first display panel overlaps a region transmitting visible light of the second display panel with the light-transmitting layer provided therebetween. It is preferred that the display region of the first display panel not overlap with a region blocking visible light of the second display panel.
