Abstract

The invention provides a display panel and a manufacturing method thereof.The display panel comprises a display area and a non-display area located on the periphery of the display area, the non-display area comprises a shadow film forming area, and the non-display area of the display panel comprises an inorganic stacking layer, a retaining wall, a light-emitting function layer, a thin film packaging layer and an auxiliary packaging layer which are stacked on a substrate. The light-emitting function layer, the thin film packaging layer and the auxiliary packaging layer extend from the display area to the shadow film forming area. The edge of the thin film packaging layer is in contact with the inner surface of the auxiliary packaging layer, and the edge of the auxiliary packaging layer is in contact with the inorganic stacking layer. According to the invention, the edges of the light-emitting functional layer and the thin film packaging layer are shrunk inwards to the shadow film forming area, and the thin film packaging layer is connected with the inorganic stacking layer by adopting the auxiliary packaging layer, so that the auxiliary packaging layer, the edges of the thin film packaging layer and the effective packaging area formed by the inorganic stacking layer are located in the shadow film forming area; therefore, the frame width of the display panel is greatly shortened, and the narrow frame design can be realized.

Description

technical field [0001] The present 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) display, also known as organic electroluminescent display, is an emerging flat panel display device, due to its simple preparation process, low cost, low power consumption, high luminous brightness, It has a wide range of working temperature adaptation, light and thin volume, fast response speed, easy to realize color display and large-screen display, easy to achieve matching with integrated circuit drivers, easy to achieve flexible display and other advantages, so it has broad application prospects. [0003] In recent years, ultra-narrow bezels have become a trend in the development of small-sized displays. Among them, the shortening of the packaging distance is a necessary condition for the ultra-narrow frame. like figure 1 As shown, the existing dis...
