ORGANIC ELECTROLUMINESCENT DISPLAY DEVICE AND DISPLAY APPARATUS

摘要

Embodiments of the present invention disclose an organic electroluminescent display device and a display apparatus. The display device includes: a base substrate, and a first electrode, an organic light emitting layer and a second electrode arranged sequentially on the base substrate, the organic light emitting layer includes a first light emitting sub-layer and a second light emitting sub-layer arranged in stack, the first light emitting sub-layer having a coverage area less than that of the second light emitting sub-layer; a connecting layer is formed by an electron-transporting material and provided between the first light emitting sub-layer and the second light emitting sub-layer; and projection areas of a pattern of the connecting layer and the first light emitting sub-layer on the base substrate are overlapped with each other. It may suppress abnormal color of light from the organic light emitting layer and improve the luminescence efficiency of the display device.
