ORGANIC LIGHT EMITTING DIODE

摘要

An organic electroluminescent device is provided to improve electric property of an electrode layer formed on a top of a spacer and a top of a sub pixel by dividing the spacer into a bar shape. An organic electroluminescent device comprises a plurality of sub pixels and a spacer(140). A plurality of sub pixels is arranged on a substrate into a matrix shape. The spacer is arranged between the sub pixels into a bar shape. A longitudinal direction width of the spacer is 6.5% ~ 25.2% of a longitudinal direction width of the sub pixel. The spacer is divided on the same line. A divided spacer has the same length or has a different length. A length ratio of the divided spacer is 10% ~ 90% of a length of three sub pixels including a non-emitting region. Three sub pixels are positioned on a line like the divided spacer.
