    • 본발명의백색유기전계발광표시장치는 n(≥2)스택구조를갖는백색유기전계발광표시장치에있어, 전하생성층과황색-녹색발광층사이에정공수송타입호스트를포함하는적색발광층이위치하는것을특징으로한다. 이에의하면, 적색발광층이발광층이외의정공수송층과전자블로킹층의역할을함으로써휘도와색재현율및 색시야각을개선할수 있다. 또한, 본발명의백색유기전계발광표시장치는전하생성층과적색발광층사이에정공수송타입호스트로이루어진보조층을추가로삽입하여전하생성층과적색발광층사이에서엑시톤의소광(quenching)을감소시킴으로써적색발광층의효율을보다더 향상시킬수 있는것을특징으로한다.
    • 本发明涉及具有n(> = 2)堆叠结构的白色有机发光显示装置。 包括空穴转移型主体的红色发光层被放置在电荷产生层和黄绿色发光层之间。 因此,由于红色发光层作为除了发光层之外的电子阻挡层和空穴传输层发挥功能,因此可以提高亮度,色彩再现和彩色视野角。 此外,白色有机发光显示装置能够通过另外插入辅助层来减少红色发光层与电荷产生层之间的激子的淬灭,从而进一步提高红色发光层的效率,该辅助层包括孔 转印型主体放入电荷产生层和红色发光层之间的间隙中。
