Abstract
【解決手段】酸化インジウム錫膜からなる透明導電膜であって、(キャリア移動度)/(キャリア濃度)が、2×10−20cm5/V/S以上であり、かつ、(キャリア移動度)×(キャリア濃度)が、200×1020cm−1/V/S以上である。

Description
まず、ガラス基板として、ソーダガラス基板を用意する。次に、ガラス基板上に亜鉛ホウ酸系ガラスペーストをスクリーン印刷すると共に、大気雰囲気下で乾燥する。その後、大気雰囲気下でガラスペーストを焼成することにより、ガラス基板上にガラスからなる光散乱層を形成する。なお、ガラス基板及び光散乱層の屈折率は、1.6とする。
続いて、光散乱層上にビスマス系ガラスペーストをアプリケータで塗布し、大気雰囲気下で乾燥する。その後、大気雰囲気下でガラスペーストを焼成することにより、光散乱層上にガラスからなる平滑層を形成する。なお、平滑層の屈折率は、1.9とする。
その後、平滑層上に、ITO膜からなる透明導電膜をスパッタリング法により形成する。スパッタリング時には、スパッタリング装置のチャンバー内に、光散乱層及び平滑層が形成されたガラス基板と、酸化インジウム錫のターゲット(成膜材料)とを配置する。この状態で、チャンバー内に、反応ガスとして、アルゴンと酸素の混合ガスを供給する。スパッタリング時のガラス基板の温度は、150℃〜350℃とする。
次に、透明導電膜上に、有機EL発光層を真空蒸着法により形成する。その後、第有機EL発光層上に、金属膜を真空蒸着法により形成する。

2.ITO膜付き基板の視感反射率(B)をISO9050に準拠した方法で測定する。[測定波長:380nm〜780nm、標準光源:D65]
3.ITO膜付き基板の光吸収率(C)=100%−(A)−(B)
4.ITO膜なし基板の視感透過率(D)をISO9050に準拠した方法で測定する。[測定波長:380nm〜780nm、標準光源:D65]
5.ITO膜なし基板の視感反射率(E)をISO9050に準拠した方法で測定する。[測定波長:380nm〜780nm、標準光源:D65]
6.ITO膜なし基板の光吸収率(F)=100%−(D)−(E)
7.ITO膜の光吸収率(G)=(C)−(F)
