Abstract
A display apparatus includes: a first organic light-emitting diode, a second organic light-emitting diode, and a third organic light-emitting diode arranged on a substrate; a first intermediate layer commonly included in the first organic light-emitting diode and the second organic light-emitting diode, the first intermediate layer including a first emission layer and a first hole transport layer; a second intermediate layer included in the third organic light-emitting diode, the second intermediate layer including a second emission layer and a second hole transport layer; and a first color converting layer, a second color converting layer, and a third color converting layer. The first emission layer and the second emission layer are configured to emit different color lights from each other, and a hole mobility of the first hole transport layer is different from a hole mobility of the second hole transport layer.
