Description
気化された有機層形成材料をノズルから吐出させることにより、該ノズルに対して相対的に移動する基材上に有機層を形成する蒸着工程を含み、前記有機層からなり基材移動方向に対して垂直な方向の幅A(mm)を有する発光領域を形成する有機EL素子の製造方法であって、
ロール状に巻き取られた帯状の前記基材を繰り出し、繰り出した前記基材を巻き取ることによって前記基材を移動させつつ、且つ、前記ノズルの開口部における前記基材移動方向と垂直方向の長さ(開口幅)をW(mm)、前記開口部と前記基材との距離をh(mm)とするとき、式W≧A+2×h(但し、W=5〜100mm、A=3〜90mm、h≦5mmである。)を満たすようにして前記蒸着工程を行なうことを特徴とする。
気化された有機層形成材料をノズルから吐出することにより、該ノズルに対して相対的に移動する基材上に有機層を形成する蒸着源を備え、有機層からなり基材移動方向に対して垂直な方向の幅A(mm)を有する発光領域を形成するように構成された有機EL素子の製造装置であって、
ロール状に巻き取られた帯状の前記基材を繰り出し、繰り出した前記基材を巻き取ることによって前記基材を移動させつつ、且つ、前記ノズルの開口部における前記基材移動方向と垂直方向の長さ(開口幅)をW(mm)、前記開口部と前記基材との距離をh(mm)とするとき、式W≧A+2×h(但し、W=5〜100mm、A=3〜90mm、h≦5mmである。)を満たすように構成されたことを特徴とする。
陽極層23を形成するための材料としては、インジウム−亜鉛酸化物(IZO)、インジウム−錫酸化物(ITO)等の各種透明導電材料や、金、銀、白金などの金属や合金材料を用いることができる。
有機層の膜厚変動を精度良く測定するために、基材上に直接有機層を形成し、形成された有機層の膜厚を測定し、測定結果から膜厚誤差を算出した。
陽極層として所定パターンのITOが形成された、幅70mm、長さ130mのフレキシブルガラス基板を用い、蒸着源を3つ用いて、該陽極層に有機層として、正孔注入層たるCuPcを膜厚25nm、正孔輸送層たるNPBを膜厚45nm、発光層たるAlq3を膜厚60nm、電子注入層たるLiFを膜厚0.5nm、陰極層たるAlを膜厚10nmとなるようにこの順で、基材上に順次形成した。また、一連のCuPc、NPB及びAlq3の形成ごとに、表1、2及び3に示すように、開口幅W、発光幅A及び距離hを変化させた。
