Abstract

The embodiment of the invention provides a display panel. In a frame region, the display panel comprises a substrate, a first inorganic layer, an encapsulation layer, a first trench portion and a second trench portion, wherein the substrate comprises a first organic substrate, an inorganic substrate and a second organic substrate; the first inorganic layer is formed on the second organic substrate; the encapsulation layer is formed on the first inorganic layer; and the first trench portion penetrates through the first inorganic layer and the second trench portion extends to the second organicsubstrate, the orthographic projection of the first trench portion on the first organic substrate falls into the orthographic projection of the second trench portion on the first organic substrate andhas an region smaller than that of the orthographic projection of the second trench portion on the first organic substrate. Due to the design of the groove structure, the extension path of the cutting crack is blocked, and the problem that the cutting crack extends to the display region to damage the display panel is avoided; compared with the prior art, the size of the whole frame region is reduced, and the narrow frame design of the display panel is achieved.

Description

technical field [0001] The present application relates to the display field, in particular to a display panel. Background technique [0002] With the development of technology and the improvement of people's quality of life, narrow bezels and full screens have gradually become the development trend in the field of display technology. [0003] To achieve a full-screen display, it is necessary to increase the screen-to-body ratio of the display panel and reduce the frame size of the display panel. In the existing technology, such as figure 1 As shown, the frame area of ​​the display panel generally includes a wiring area 101, an effective packaging area 102, a crack prevention area 103, and a cutting area 104; the display panel includes a substrate 110, a first inorganic layer 120, The second inorganic layer 130 , the metal wiring layer 140 , the organic layer 150 , and the encapsulation layer 160 . In the anti-crack area 103, the second inorganic layer 130 is set in a gull...
