ABSTRACT:
An organic light-emitting display device is provided which achieves high efficiency by reducing the number of steps for vapor deposition using a mask with a fine pattern and photolithography. A blue light-emitting portion (B), a green light-emitting portion (G) and a red light-emitting portion (R) placed on a substrate10have a thickness relationship represented as (blue light-emitting portion (B)<green light-emitting portion (G)=red light-emitting portion (R)), so that the green light-emitting portion (G) and the red light-emitting portion are formed with common deposition steps. In addition, an electron injection layer2and an electron transport layer3between a lower electrode and an organic light-emitting layer4are formed with common depositions steps in the light-emitting portions (B, G and R).
