Abstract

The embodiment of the invention provides a mask plate, a display panel and a manufacturing method of the display panel, and a display device, which relate to the technical field of display, and are used for solving the problem that it is difficult to prepare a special-shaped OLED display with intermediate holes in the prior art. The display panel comprises a hollow region and a display region surrounding the hollow region, wherein the display region is provided with a plurality of organic light emitting devices, the hollow region is not provided with an organic light emitting device, the organic light emitting device comprises an anode layer, a cathode layer, a light emitting layer and a functional layer, and the functional layer comprises a plurality of irregularities. The display panel is used for realizing screen display.

Description

【Technical field】 [0001] The invention relates to the field of display technology, in particular to a display panel, a mask plate, a manufacturing method of the display panel, and a display device. 【Background technique】 [0002] With the continuous development of display technology and the diversified needs of users for display devices, there are such figure 1 The shown special-shaped display with a hole in the middle has received more and more attention, wherein, figure 1 It is a schematic diagram of the shape of a special-shaped display with a hole in the middle in the prior art. [0003] However, for the OLED display, because the functional film layers such as the electron transport layer and the electron injection layer included in it all need to be formed by evaporation, therefore, in the production figure 1 For the OLED special-shaped display of the shown shape, all film layers need to avoid the region 1' of the middle hole, which increases the difficulty of prepara...
