As shown in fig. 2 and fig. 3, in the present embodiment, the display device 1 of the invention includes a display panel 10, wherein the display panel 10 includes a first substrate 110, a packaging region 120, a light shielding layer 130, a second substrate 140, a retaining wall 150, a first polarizer 111, a first conductive layer 112, a first flexible layer 113, a second polarizer 121, a metal unit 122, and a second flexible layer 123.
The first substrate 110 is a hard glass substrate, which has a good light-transmitting effect and a certain carrying capacity, and can protect other films.
The first polarizer 111 is disposed on a side surface of the first substrate 110, the polarizer is a necessary film for implementing liquid crystal display, and the first polarizer 111 can pass through light rays with a specific angle, so as to implement a display frame and a closed frame of the display panel 10.
The encapsulation region 120 is disposed at a frame of the display panel 10, and the encapsulation region 120 is provided with a retaining wall 150 for preventing external water vapor from entering the display panel 10 through a gap between the first substrate 110 and the second substrate 140, thereby causing poor display of the display panel 10.
The light shielding layer 130 is disposed on a side surface of the first substrate 110 close to the second substrate 140, and since the encapsulation region 120 is a non-display region, the light shielding layer 130 is disposed in the encapsulation region 120, thereby preventing the light leakage phenomenon from occurring in the encapsulation region 120.
The light-shielding layer 130 is usually made of a photoresist material, and due to the characteristics of the photoresist material, water vapor easily enters the inside of the display panel 10 through the photoresist material, thereby causing damage to metal components inside the display panel 10.

Because the gaps are formed between the light-shielding units 131 and the gaps are also formed between the metal units 122, the retaining wall 150 can be cured by means of double-side illumination when the retaining wall 150 is prepared, so that the hardness of the retaining wall 150 can be improved, and the service life of the retaining wall 150 can be prolonged.
The second polarizer 121 is disposed on a side surface of the second substrate 140 away from the first substrate 110, the polarizer is a necessary film for implementing liquid crystal display, the first polarizer 111 and the second polarizer can pass through light rays with a specific angle, and the light rays passing through the first polarizer 111 and the second polarizer 121 are perpendicular to each other, so as to implement a display frame and a closed frame of the display panel 10.
The second flexible layer 123 is disposed on a side surface of the metal unit 122 close to the first substrate 110, and serves to protect the metal unit 122 and also to buffer damage to the metal unit 141 caused by the retaining wall 150.
