Abstract

The invention discloses a display panel and a manufacturing method thereof, comprising a flat display area and at least one curved display area adjacent to the flat display area; the display panel further includes a light-emitting functional layer; the light-emitting functional layer includes an anode layer, and the anode layer includes The main anode sublayer and the secondary anode sublayer are located in the curved display area and are arranged at intervals, wherein the part of the display panel located in the flat display area faces the first direction, the main anode sublayer faces the second direction, and the secondary anode sublayer faces the first direction. Three directions, the angle between the third direction and the first direction is smaller than the angle between the second direction and the first direction. By setting the secondary anode sublayer, the present invention can compensate the light lost in the curved display area under a large viewing angle due to bending, can effectively reduce the display unevenness and color shift in the curved display area and the flat display area, and improve the display panel. display effect.

Description

technical field [0001] The present invention relates to the field of display technology, and in particular, to a display panel and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) is widely used due to its advantages of flexibility and bendability, high luminous efficiency and fast response speed. At present, in order to improve the screen ratio of OLED display panels, OLED display The panel is designed as a curved screen structure including a flat area and a curved area with a certain arc with the flat area. However, due to the light-emitting characteristics of the OLED display panel, the brightness displayed by the pixels under different viewing angles will vary greatly, resulting in a curved screen structure. There is a large difference in brightness between the flat area and the curved area, and even the problem of color cast, which affects the user experience.
