Abstract

The invention provides a display panel, which comprises a substrate, a display area located on the substrate, at least one retaining wall arranged on the periphery of the display area, a first inorganic layer, an organic buffer layer and a second inorganic layer, wherein one side, far away from the substrate, of the retaining wall is a protruding curved surface; the first inorganic layer, the organic buffer layer and the second inorganic layer sequentially cover the display area; the first inorganic layer covers the display area; the first inorganic layer is at least in contact with one retaining wall; the organic buffer layer covers the display area; the edge of the organic buffer layer does not exceed the edge of the first inorganic layer; and the edge of the second inorganic layer exceeds the edge of the organic buffer layer. The invention further provides a manufacturing method of the display panel. According to the display panel and the manufacturing method thereof, the display panel can be prevented from being eroded and damaged by water vapor and oxygen and the packaging airtightness of the display panel is improved.

Description

technical field [0001] The invention relates to the field of display technology, in particular to a display panel and a manufacturing method thereof. Background technique [0002] Organic Light-Emitting Diode (OLED) has the advantages of fast response, wide temperature range, self-illumination, flexible display, etc. The third-generation display technology after Liquid Crystal Display (LCD) / Light Emitting Diode (LED). With the continuous increase of market demand, the field of OLED technology has achieved extensive coverage in the display field. [0003] Since the organic materials used in OLED display devices are particularly sensitive to external water and oxygen, OLED display devices require more stringent packaging conditions than liquid crystals. Especially in the field of flexible displays, the packaging structure of OLED display devices not only needs to fully block the erosion of external water and oxygen on the organic materials in OLED display devices, but also e...
