Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, but not to limit the present invention. In addition, it should be noted that, for the convenience of description, only some structures related to the present invention are shown in the drawings but not all structures.

[0037] As mentioned in the background art, the existing display device has a problem of low yield after reliability test. The inventors have found through research that the reason for the above problems is that during the reliability test, the high temperature and high pressure environment causes some film layers to shrink inward, which leads to a large stress between the film layers arranged in the stack, and then the film layer peeling phenomenon. Exemplarily, figure 1 It is a schematic cross-sectional structu...

Abstract

The embodiment of the invention discloses a display device and a preparation method thereof. The display device comprises a display panel; a polarizing layer which is located on one side of the display panel, and the polarizing layer comprises a main body part and an extending part; a protection layer, the protection layer and and the polarization layer are located on the same side of the display panel, the protection layer is located on the side, facing the extending part, of the main body part, the extending part comprises a side surface close to the side of the protection layer, a lower surface close to the side of the display panel and an upper surface away from the side of the display panel, and the protection layer makes contact with the side surface of the extending part, and contacts at least one of the upper surface and the lower surface of the extension part. According to the technical scheme provided by the embodiment of the invention, the extending part of the polarization layer extends into the protection layer, so that the protection layer is in contact with at least one of the upper surface and the lower surface of the extending part while being in contact with the side surface of the extending part, and the contact area between the polarization layer and the protection layer is increased, therefore, the polarization layer is not easy to shrink inwards, and the stripping phenomenon of the film layer can be improved.

Description

technical field [0001] Embodiments of the present invention relate to the field of display technology, and in particular to a display device and a manufacturing method thereof. Background technique [0002] As the resolution of the display device is getting higher and higher, in order to reduce the occupation of the frame of the display device as much as possible, various manufacturers are trying to narrow the frame of the display device. [0003] At present, in order to realize the narrow frame design, the film boundary structure of the lower frame of the screen adopts a centralized design. However, during the reliability test, peeling tends to occur between the laminated layers of the lower frame, which reduces the yield of the display device. Contents of the invention [0004] Embodiments of the present invention provide a display device and a manufacturing method thereof, so as to improve the yield of the display device. [0005] In a first aspect, an embodiment of t...
