Manufacturing method for electroluminescence display apparatus

摘要

A method of manufacturing an electroluminescent display apparatus includes: discharging first droplets of the fluid luminescent material from the first nozzles to the target discharge areas when the first nozzles are positioned in an area above the target discharge areas so that all of the first droplets are arranged in the target discharge areas on different X-axis direction positions so as not to overlap each other when viewed in the Y-axis direction; and discharging second droplets of fluid luminescent material from the second nozzles to the target discharge areas to which the first droplets have been discharged when the second nozzles are positioned in the area above the target discharge areas after a predetermined period of time passed since the discharge of the first droplets to the target discharge areas.

主权项

1. A method of manufacturing an electroluminescent display apparatus, comprising;
providing a substrate having a carrier substrate, a circuit element layer formed on the carrier substrate, a plurality of pixel electrodes formed on the circuit element layer, and a bank formed between the plurality of pixel electrodes, a plurality of target discharge areas being defined with the bank and the pixel electrodes; providing a discharge apparatus including a stage, a discharge head unit having a first nozzle row of first nozzles and a second nozzle row of second nozzles, and a scanning unit for moving at least one of the stage and the discharge head unit with respect to the other; mounting the substrate on the stage of the discharge apparatus such that the target discharge areas are positioned to extend along a X-axis direction; moving one of the stage and the drive head unit relative to the other in a Y-axis direction, the Y-axis direction intersecting with the X-axis direction; discharging first droplets of fluid luminescent material from the first nozzles to the target discharge areas when the first nozzles are positioned in an area above the target discharge areas so that all of the first droplets are arranged in the target discharge areas on different X-axis direction positions so as not to overlap each other when viewed in the Y-axis direction; discharging second droplets of the fluid luminescent material from the second nozzles to the target discharge areas to which the first droplets have been discharged when the second nozzles are positioned in the area above the target discharge areas after a predetermined period of time passed since the discharge of the first droplets to the target discharge areas; and disposing a plurality of opposite electrodes so as to cover the luminescent material and the bank.
