Abstract: Provided is a display device with extremely high resolution, a display device with higher display quality, a display device with improved viewing angle characteristics, or a flexible display device. Same-color subpixels are arranged in a zigzag pattern in a predetermined direction. In other words, when attention is paid to a subpixel, another two subpixels exhibiting the same color as the subpixel are preferably located upper right and lower right or upper left and lower left. Each pixel includes three subpixels arranged in an L shape. In addition, two pixels are combined so that pixel units including subpixel are arranged in matrix of 3×2.

Abstract: In order to provide a highly reliable organic EL element, a first step in which a deposition material is heated and vaporized in a deposition chamber in which the pressure is reduced and a second step in which a layer included in an EL layer is deposited in the deposition chamber are performed while exhaustion is performed and the partial pressure of water in the deposition chamber is measured with a mass spectrometer. Alternatively, the deposition chamber in the deposition apparatus includes a deposition material chamber and is connected to an exhaust mechanism. The deposition material chamber is separated from the deposition chamber by a sluice valve, includes a deposition material holding portion including a heating mechanism, and is connected to a mass spectrometer and an exhaust mechanism.

Abstract: A lighting device is formed using a light-emitting element by a more simplified method. The lighting device includes a light-emitting element including a light-emitting layer between a first electrode and a second electrode, a substrate provided with the light-emitting element and an uneven region around the periphery of the light-emitting element, a sealing substrate facing the substrate, connection electrodes connected to the first electrode and the second electrode and formed over the uneven region, and a sealant for bonding the substrate and the sealing substrate. The connection electrodes are each formed using a conductive paste, and the sealant is in contact with the connection electrodes and the uneven region provided around the periphery of the light-emitting element.
