Assignee: SAMSUNG ELECTRONICS CO., LTD.
Field: Semiconductors (Electrical engineering)
Classification: CPC H | IPC H

Claim 13:
14. A method of manufacturing a display device, comprising:
forming a first alignment line and a second alignment line on a mother substrate;
forming an outer bank on the first alignment line and the second alignment line;
applying a solution comprising light emitting elements to a first opening defined by the outer bank;
aligning the light emitting elements by forming an electric field by applying a first alignment voltage to the first alignment line and applying a second alignment voltage to the second alignment line; and
removing the solution by volatilizing the solution,
wherein the aligning of the light emitting elements by forming the electric field comprises:
generating a first alignment signal, and a second alignment signal and a first emission timing signal;
transmitting the first alignment signal and the second alignment signal to a first alignment pad electrically connected to the first alignment line and a second alignment pad electrically connected to the second alignment line through first probe pins of a first electric-field-applying module; and
irradiating light to the mother substrate by transmitting a first emission driving signal to light emitting diode arrays of a first light-irradiating module according to the first emission timing signal, and

wherein a period of the first emission timing signal is same as a period of the second alignment signal.
