    Abstract: A method for operating an electronic device, which is easy on eyes, is provided. The electronic device includes a display device including a light-emitting device and a light-receiving device, and a lens. The method includes a step of displaying an image for focus adjustment of a user's eye; a step of detecting a spot diameter of first light reflected by the user's eye; a step of moving the lens and detecting a spot diameter of second light reflected by the user's eye; a step of determining whether the spot diameter of the second light is smaller than the spot diameter of the first light; a step of further moving the lens and detecting a spot diameter of the third light reflected by the user's eye in the case where the spot diameter of the second light is smaller than the spot diameter of the first light; a step of determining whether the spot diameter of the third light is smaller than the spot diameter of the second light; and a step of moving the lens to a position at which the spot diameter of the first light has been detected, in the case where the spot diameter of the second light is larger than the spot diameter of the first light.

    Abstract: A display device which exhibits light with high color purity is provided. A display device with low power consumption is provided. An embodiment is a display device which includes a first pixel electrode, a second pixel electrode, a light-emitting layer, a common electrode, a first protective layer, and a semi-transmissive layer. The light-emitting layer includes a first region positioned over the first pixel electrode and a second region positioned over the second pixel electrode. The common electrode is positioned over the light-emitting layer. The first protective layer is positioned over the common electrode. The semi-transmissive layer is positioned over the first protective layer. Reflectivity with respect to visible light of the semi-transmissive layer is higher than reflectivity with respect to visible light of the common electrode. The semi-transmissive layer does not overlap with the first region and overlaps with the second region. For example, the semi-transmissive layer may include an opening in a position overlapping with the first region.

    Abstract: To provide a display device that is suitable for increasing in size, a display device in which display unevenness is suppressed, or a display device that can display an image along a curved surface. The display device includes a first display panel and a second display panel each including a pair of substrates. The first display panel and the second display panel each include a first region which can transmit visible light, a second region which can block visible light, and a third region which can perform display. The third region of the first display panel and the first region of the second display panel overlap each other. The third region of the first display panel and the second region of the second display panel do not overlap each other.
