Title:
有機エレクトロルミネッセンス素子およびその製造方法
Document Type and Number:
Japanese Patent JP3991605
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To enhance light emitting efficiency of t an organic luminous layer of an electroluminescence organic element without reducing the aperture rate. SOLUTION: A light transparent positive electrode layer 3, an organic luminous layer 4, and a light reflective cathode layer 5 are made to exist in the whole surface of one picture element region. At the positive electrode layer 3, organic luminous layer 4 and cathode layer 5, slopes 62 to 64 to protrude toward the cathode layer 5 side from the positive electrode layer 3 are installed. By this, the light H which is generated at the organic luminous layer 4, and which is emitted in parallel with a laminated face of laminated body S is made to be reflected by the slope 63 of a boundary between the organic luminous layer 4 and the cathode layer 5, and it is made to emit to the positive electrode layer 3 side.
