Abstract:
A light-emitting device (10) includes a substrate (100), a first electrode (110), an organic layer (120), a plurality of first metal-containing layers (132), a metal compound-containing layer (134), and a second metal-containing layer (136). The first electrode (110) is located over the substrate (100), and has a light transmitting property. The organic layer (120) is located over the first electrode (110). The plurality of first metal-containing layers (132) are located over the organic layer (120), and has a light shielding property. The metal compound-containing layer (134) covers the plurality of first metal-containing layers (132), and has a light transmitting property. The second metal-containing layer (136) covers the metal compound-containing layer (134), and has a light transmitting property.
