Abstract:
1. A light-emitting device, comprising: an operating substrate, wherein an entirety of the operating substrate is flat; a plurality of first light-emitting diode epitaxial stack units arranged in a form of multiple first rows parallel to each other and capable of emitting a first major emission wavelength; and a plurality of second light-emitting diode epitaxial stack units arranged in a form of multiple second rows parallel to each other and capable of emitting a second major emission wavelength different from the first major emission wavelength, wherein the multiple first rows and the multiple second rows are alternately disposed, wherein each of the plurality of first light-emitting diode epitaxial stack units has a first rectangular border from a top view, each of the plurality of second light-emitting diode epitaxial stack units has a second rectangular border from a top view, and one side of the first rectangular border is neither parallel nor perpendicular to one side of the second rectangular border, and wherein at least one of the first light-emitting diode epitaxial stack units is devoid of an original growth substrate on which the at least one of the first light-emitting diode epitaxial stack units is originally formed.
