Abstract: A high-resolution display device is provided. The display device includes a first light-emitting device, a second light-emitting device, a first insulating layer, a second insulating layer, a first coloring layer, and a second coloring layer. The first light-emitting device includes a first pixel electrode, a first layer, and a common electrode in this order over the first insulating layer. The second light-emitting device includes a second pixel electrode, a second layer, and the common electrode in this order over the first insulating layer. The first insulating layer includes a groove including a region overlapping with the first pixel electrode and a region overlapping with the second pixel electrode. The second insulating layer overlaps with a side surface of the first layer, a side surface of the second layer, and the groove. The common electrode includes a portion positioned over the second insulating layer. The first coloring layer overlaps with the first light-emitting device.

Abstract: A highly reliable display device is provided. The display device includes a first light-emitting element, a second light-emitting element adjacent to the first light-emitting element, a first insulating layer provided between the first light-emitting element and the second light-emitting element, and a second insulating layer over the first insulating layer. The first light-emitting element includes a first conductive layer, a second conductive layer covering an upper surface and a side surface of the first conductive layer, a first EL layer covering an upper surface and a side surface of the second conductive layer, and a common electrode over the first EL layer. The second light-emitting element includes a third conductive layer, a fourth conductive layer covering an upper surface and a side surface of the third conductive layer, a second EL layer covering an upper surface and a side surface of the fourth conductive layer, and the common electrode over the second EL layer.

Abstract: [Object] Disclosed is a compound useful as an active ingredient for a pharmaceutical composition having an ?-amylase inhibitory activity, particularly a pharmaceutical composition for the treatment of diabetes. [Solution] An investigation has been made on a compound having an ?-amylase inhibitory activity among the compounds produced by Streptomyces sp. strain 6982, which is a actinomycetes belonging to the genus Streptomyces, and it was confirmed that an aminosugar compound has an ?-amylase inhibitory activity, thus completing the invention. The aminosugar compound of the present invention has an ?-amylase-inhibitory activity, and therefore can be used as a prophylactic or therapeutic agent for diabetes, obesity, NASH (non-alcoholic steatohepatitis), particularly as an ameliorating agent for postprandial blood glucose elevation.
