Abstract
A light emitting device includes a substrate elongated in a lengthwise direction; a plurality of LED chips disposed on the substrate in an intermediate region in widthwise direction, and aligned along the lengthwise direction at a distance of 80 μm or less; and interconnection wirings formed on regions outside the intermediate region in the widthwise direction; wherein each of the LED chips has a p-side electrode disposed on the substrate, a p-type semiconductor layer disposed on the p-side electrode, an active layer formed on the p-type semiconductor layer, and an n-type semiconductor layer formed on the active layer, and has a region in which the n-type semiconductor layer, the active layer, and the p-type semiconductor layer are patterned, and an n-side electrode formed selectively on a surface of the n-type semiconductor layer and connected to the p-side electrode of an adjacent LED chip through the interconnection wiring.
