Abstract

The invention discloses a top-emission type organic electroluminescent display panel and a manufacturing method thereof as well as a display device. The top-emission type organic electroluminescent display panel comprises a substrate base plate, and a white organic light-emitting diode and a film packaging layer both orderly arranged on the substrate base plate, wherein the film packaging layer comprises at least two film layers and at least one organic film layer, all of which are arranged alternately, wherein one organic film layer is a color filter layer comprising at least three optical filters different in color and capable of realizing all-color display. As one organic film layer in the film packaging layer is the color filter layer, no color filter layer needs to be arranged independently above the film packaging layer, and therefore, the number of the films of the display panel can be reduced, the film structure can be simplified, the process can be shortened and the manufacturing cost can be reduced; in addition, the optical path from the luminous layer to the color filter layer can be shortened, and consequently, the luminous efficiency and the display effect can be improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a top-emission organic electroluminescence display panel, a manufacturing method thereof and a display device. Background technique [0002] At present, organic electroluminescent display devices (Organic Electroluminescent Display, OLED) have gradually become the mainstream in the display field due to their excellent performances such as low power consumption, high color saturation, wide viewing angle, thin thickness, and flexibility. OLED can be divided into two types: bottom emission type and top emission type according to the way of light emission. The light emission of bottom emission type OLED comes from the side of the substrate substrate, while the light emission of top emission type OLED comes from the top. [0003] In order to realize the full colorization of large-sized OLED panels, it is generally realized by stacking a top-emitting white organic light emitting diode...
