摘要:
The present invention provides an organic electroluminescence (EL) element that suppresses leakage current flowing between an upper electrode and an under electrode through an organic layer. The organic EL element (51) is provided at a pixel region (R11) surrounded by a bank (3) on the substrate, and comprises: an organic layer (9) including at least one layer of the light-emitting layer (6); an upper electrode (7) and an under electrode (2) which hold the organic layer (9) therebetween; and a leakage current block layer (5) formed between the upper electrode (7) and the under electrode (2) at the boundary region (R12) between the pixel region (R11) and the bank region (R13), and formed between the upper electrode (7) and the under electrode (2) at the boundary region (R12) between the pixel region (R11) and the bank region (R13). The electric resistance of the leakage current block layer (5) in a thickness direction of the substrate is higher than the electric resistance of the organic layer (9) provided between the leakage current block layer (5) and the first electrode (2) in the thickness direction of the substrate.
