| 摘要 |
An organic electroluminescent device includes: a first electrode and a first carrier transport layer (CTL) on a substrate having sub-pixels that include a first light emitting area (LEA) for a first color, a second LEA for a second color, and a third LEA for a third color, a first hydrophilic material on the first CTL in the first LEA, a first color light emitting layer (LEL) on the first hydrophilic material in the first LEA, a second hydrophilic material on the first CTL in the second LEA, a second color LEL on the second hydrophilic material in the second LEA, a third hydrophilic material on the first and second color LELs and on the first CTL in the third LEA, a third color LEL on the third hydrophilic material, a second CTL on the third color LEL, and a second electrode on the second CTL.
