A light emitting device includes a printed circuit board (PCB) including a connection pad, a base substrate mounted on the PCB and including a pixel region and a pad region, light emitting structures arranged on the pixel region, a barrier rib structure disposed on the pixel region and disposed at a vertical level different from the light emitting structures, the barrier rib structure including barrier ribs connected with each other to define each of pixel spaces, a phosphor layer filling each pixel space, a dam structure surrounding the barrier rib structure, a pad disposed on the pad region and adjacent to at least one side of an outer boundary of the light emitting structures, a bonding wire connecting the connection pad to the pad, and a molding structure covering the pad, the connection pad, the bonding wire, and at least a portion of the dam structure.

Light emitting device and method of manufacturing the same

A light emitting device is provided. The light emitting device includes a first semiconductor layer; a second semiconductor layer provided on a bottom surface of the first semiconductor layer; an active layer interposed between the first semiconductor layer and the second semiconductor layer; a dielectric layer provided on a bottom surface of the second semiconductor layer; a plurality of first n-contacts provided on a first etched surface of the first semiconductor layer; and a plurality of first p-contacts and a plurality of second p-contacts provided on the bottom surface of the second semiconductor layer. One first n-contact is disposed along a first edge region of the first semiconductor layer, one first p-contact is closer to the one first n-contact than one second p-contact, and an area of the one first p-contact is greater than an area of each of the second p-contacts.

Light emitting device

A semiconductor light-emitting device includes a light-emitting structure including a first semiconductor layer, an active layer and a second semiconductor layer sequentially stacked. A connection electrode is positioned above the light-emitting structure. The connection electrode includes a connection metal layer electrically connected to at least one of the first and second semiconductor layers. A UBM pattern is on the connection electrode. A connection terminal is on the UBM pattern. The connection metal layer includes a first metal element. A heat conductivity of the first metal element is higher than that of gold (Au). The connection terminal includes a second metal element. A first reactivity of the first metal element with the second metal element is lower than a second reactivity of gold (Au) with the second metal element.
