Abstract
The present invention provides an assembly substrate used in a method for manufacturing a display device which mounts semiconductor light emitting devices on a predetermined position of an assembly substrate by using an electric field and a magnetic field. Specifically, the assembly substrate is characterized by comprising: a base part; a plurality of assembly electrodes formed extending in one direction and disposed on the base part; a dielectric layer laminated on the base part so as to cover the assembly electrodes; a partition wall formed on the base part and including a plurality of grooves for guiding the semiconductor light emitting devices to a predetermined position; and a metal shielding layer formed on the base part, wherein each of the plurality of grooves penetrates the partition wall so as to form a seating surface on which the guided light emitting devices are seated, and the metal shielding layer overlaps with a part of the seating surface such that an electric field formed on a part of the seating surface is shielded.
