Patent ID: 8119189

Claim:
A method of manufacturing an electroluminescence display device comprising: providing a first evaporation source in an evaporation chamber; providing a second evaporation source in a second chamber connected to the evaporation chamber wherein each of the first and second evaporation sources has a first direction and a second direction different from each other, each of the first and second evaporation sources being longer in the first direction than in the second direction; disposing a substrate in the evaporation chamber; fixing a mask to the substrate wherein the mask is located between the substrate and the first evaporation source; evaporating a first material from the first evaporation source to deposit the first material over the substrate in the evaporation chamber; transferring the second evaporation source from the second chamber into the evaporation chamber after evaporating the first material; evaporating a second material from the second evaporation source to deposit the second material over the substrate in the evaporation chamber; and repeatedly moving a relative position of the second evaporation source with respect to the substrate along the second direction during the step of evaporating the second material in order that a same portion of the substrate is coated with the second material at least twice, wherein the first material and the second material are compositionally different material.
