Abstract

Embodiments of the present invention provide a mask plate, a display panel, a method for manufacturing a display panel, and a display device, which relate to the field of display technology and are used to solve the problem of difficulty in preparing a special-shaped OLED display with a hole in the middle in the prior art. . The above-mentioned display panel includes a hollow area and a display area surrounding the hollow area. The display area is provided with a plurality of organic light-emitting devices, and the hollow area is not provided with an organic light-emitting device. The organic light-emitting device includes an anode layer, a cathode layer, a light-emitting layer and a functional layer. The functional layer Includes a plurality of unevennesses. The above-mentioned display panel is used to realize 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...
