Wherein, the binding end 111 is located in the binding area (OLB area), and the decorative strip 400 covers the binding end 111, which can simultaneously play the roles of protecting the binding end 111 and protecting the COF binding end.

[0045] Specifically, the display panel 100 can be a liquid crystal display panel, the first substrate 110 can be an array substrate, the second substrate 120 can be a color film substrate, and the first substrate 110 and the second substrate 120 further comprise a liquid crystal layer. The display panel 100 comprises a display area AA and a non-display area NA located on at least one side of the display area AA, the first polarizer 210 covers the display area AA, and the end of the first polarizer 210 extends to the non-display area NA. The decorative strip 400 is located in the non-display area NA and covers the OLB area, and the decorative strip 400 covers the binding end 111 to protect the binding end 111. One end of the decorative strip 400 close to the first polarizer 210 is attached to the upper surface of the second substrate 120 and abuts the end of the first polarizer 210, and the other end of the decorative strip 400 is connected to the glue frame 300 below, and the glue frame 300 can be used to support and fix the decorative strip 400.

[0046] In the embodiment, the decorative strip 400 and the first polarizer 210 are arranged on the surface of the second substrate 120, that is, the decorative strip 400 and the first polarizer 210 are located in the same plane, so that the gap between the decorative strip 400 and the first polarizer 210 in the vertical direction (that is, the Y direction in the figure) can be avoided. Meanwhile, the second substrate 120 can provide support and fixing for the end of the decorative strip 400 close to the first polarizer 210, so as to ensure the connection stability of the abutting part of the decorative strip 400 and the first polarizer 210, and further ensure the flatness of the surface of the display device 10, so as to improve the appearance effect of the display device 10.

[0047] In some embodiments, referring to Figures 2-4 , the display device 10 comprises a plurality of chip-on-film 130, and the plurality of chip-on-film 130 are arranged at intervals along the third direction Z, and there is a gap 131 between adjacent chip-on-film 130.

[0048] The glue frame 300 is provided with a plurality of support portions 330, and the plurality of support portions 330 are arranged at intervals along the third direction Z, and the orthogonal projection of the support portion 330 on the glue frame 300 is located in the range of the orthogonal projection of the gap 131 on the glue frame 300, and the decorative strip 400 is connected with the support portion 330.

The bonding layer 340, for example, can be a dispensing or foam tape, which is used to bond and fix the support portion 330, so as to ensure the connection stability of the decorative strip 400.

[0051] In some embodiments, the thickness of the decorative strip 400 ranges from 0.1 mm to 0.19 mm. Since the thickness of the first polarizer 210 usually ranges from 0.1 mm to 0.19 mm, in order to reduce the step difference between the decorative strip 400 and the first polarizer 210, the thickness of the decorative strip 400 is close to or equal to the thickness of the polarizer.

[0052] In an embodiment, the thickness of the decorative strip 400 is the same as the thickness of the first polarizer 210, so that the side surface of the decorative strip 400 away from the display panel 100 is flush with the side surface of the first polarizer 210 away from the display panel 100, so that there is no step between the surface of the decorative strip 400 and the surface of the first polarizer 210, to further improve the appearance of the display device 10.

The metal layer is a sheet structure of metal material. Since the thickness of the decorative strip 400 needs to be similar to the thickness of the first polarizer 210, and the thickness of the first polarizer 210 is relatively thin, in order to ensure the rigidity of the decorative strip 400, the metal material is used as the main structure of the decorative strip 400, and the metal layer has good flatness, which is beneficial to improve the appearance. The color of the decorative layer is the same as or similar to the color of the first polarizer 210, in order to ensure the appearance consistency of the decorative strip 400 and the first polarizer 210.

[0054] In some embodiments, the decorative layer can be formed by paint spraying treatment, that is, the surface of the metal layer is sprayed with paint having the same color as or similar to the color of the first polarizer 210, to obtain the decorative strip 400 having the same appearance color as or similar to the first polarizer 210.

[0055] For example, the surface of a metal layer with a thickness of 0.1 mm can be treated by paint spraying, to form a decorative layer having the same color as the first polarizer 210. The total thickness of the metal layer and the decorative layer after paint spraying treatment is 0.15 mm, so that the thickness of the decorative strip 400 is equal to the thickness of the first polarizer 210, and the thickness of the first polarizer 210 is 0.15 mm, so that the decorative strip 400 has the same appearance effect as the first polarizer 210.

[0057] Specifically, the planar portion 410 can be rectangular, including a first side 401, a second side 402, a third side 403 and a fourth side 404 connected head to tail, wherein the first side 401 is in contact with the first polarizer 210, and the second side 402, the third side 403 and the fourth side 404 extend to the side wall of the middle frame 600 respectively, so as to cover the gap between the end of the first polarizer 210 and the side wall of the middle frame 600, and ensure better appearance effect.

[0058] In some embodiments, referring to Figures 3-7 , the decorative strip 400 can be of a bent structure, including a planar portion 410 and at least one side portion 420, the planar portion 410 being located at the light-emitting side of the display panel 100 and parallel to the surface of the display panel 100, and the side portion 420 being arranged on at least one side of the planar portion 410 away from the first polarizer 210, one end of the side portion 420 being connected to the planar portion 410 and the other end extending towards the display panel 100.

[0059] Specifically, the side portion 420 can be located between the glue frame 300 and the side wall of the middle frame 600, and the side portion 420 is perpendicular to the planar portion 410. The side portion 420 can be connected to at least one of the second side 402, the third side 403 and the fourth side 404 of the planar portion 410. When the decorative strip 400 is of a bent structure, it is beneficial to improve the sealing effect and the stability of the connection at the edge.

[0060] In an embodiment, referring to Figure 6 , the decorative strip 400 can include one side portion 420, one end of the side portion 420 being connected to the third side 403, and the third side 403 being opposite to the first side 401, i.e., the decorative strip 400 is of an L shape.

[0061] In an embodiment, referring to Figure 7 , the decorative strip 400 can include three side portions 420, the three side portions 420 being connected to the second side 402, the third side 403 and the fourth side 404 respectively. Further, the adjacent side portions 420 can be connected.

[0062] Specifically, the planar portion 410 and the side portion 420 can be integrally formed, for example, the edges of a planar metal sheet can be bent to form the decorative strip 400 of an L-shaped cross section, but are not limited thereto.

[0063] The display device provided by the present application comprises a decoration strip, the decoration strip is located at at least one end of the first polarizer along a direction parallel to the first polarizer, and the end of the decoration strip close to the first polarizer abuts against the end of the first polarizer close to the decoration strip. By abutting the end of the decoration strip against the end of the first polarizer, the present application avoids the gap between the decoration strip and the first polarizer, and ensures that the absolute value of the difference between the first distance between the side surface of the decoration strip away from the display panel and the display panel and the second distance between the side surface of the first polarizer away from the display panel and the display panel is less than or equal to 0.05 mm, so that the display device has no obvious step feeling, and the display device has better appearance effect.
