Abstract:
1. A manufacturing method of a display device having a display panel on which a plurality of display pixels are arrayed, the method using equipment including a printer head which comprises a solution jetting unit having a nozzle for jetting a material solution and coating it on regions where the display pixels are to be formed, and a solution heating unit disposed adjacent to the solution jetting unit for heating and drying the material solution coated on the regions where the display pixels are to be formed, wherein the solution heating unit and the solution jetting unit are arranged in a direction perpendicular to a relative scan-moving direction of the printer head, the method comprising: a step of heating and drying the material solution, in which while the nozzle of the solution jetting unit is coating on a first column of the regions where the display pixels are to be formed, the solution heating unit heats and dries the material solution coated by the nozzle of the solution jetting unit on a second column of the regions where the display pixels are to be formed, wherein the material solution on the second column has been coated before the material solution on the first column is coated, and the first and second columns run along the scan-moving direction on the display panel.
