摘要： An organic light-emitting display device is discussed in which an auxiliary hole transport layer is provided in contact with a hole injection layer in at least one sub-pixel, thereby preventing current leakage to an adjacent sub-pixel due to a common layer having high hole mobility and consequently preventing the adjacent sub-pixel from being unintentionally turned on.
