Abstract:
1. A light emitting device, comprising: a substrate; light emitting cells spaced apart from one another on the substrate, each light emitting cells comprising a first-type semiconductor layer, an active layer, and second-type semiconductor layer, wherein each of the light emitting cells has an upper surface facing away from the substrate and an opposing lower surface; first-type electrodes spaced apart from one another and disposed between the substrate and the light emitting cells, each first-type electrode being electrically connected to a corresponding first-type semiconductor layer, and each first-type electrode comprising an extension extending toward an adjacent light emitting cell; wires disposed on sides of the light emitting cells; second-type electrodes disposed on the upper surfaces of the light emitting cells; and a first insulating layer disposed on side surfaces of the light emitting cells and between the second-type electrodes and the upper surfaces of the light emitting cells, wherein, each second-type electrode comprises a first portion that directly contacts the upper surface of the corresponding light emitting cell, and a second portion that extends from a corresponding one of the wires to the first portion, and is insulated from the upper surface by the first insulating layer, and the wires connect the extensions of the first-type electrodes and the corresponding second-type electrodes, each wire being insulated from the sides of the light emitting cells by the first insulating layer.
