In the embodiment of the present application, the light shielding layer 36 is provided with a plurality of first light holes 36a penetrating through the light shielding layer 36, and one of the first light holes 36a is located in one of the peep-preventing sub-pixel areas a21, i.e. the positions of the first light holes 36a are in one-to-one correspondence with the positions of the peep-preventing sub-pixel areas a 21. The first light holes 36a are located corresponding to the middle portion of the reflective element 34, i.e. the front projection of the first light holes 36a onto the encapsulation layer 35 coincides with the front projection of the middle portion of the reflective element 34 onto the encapsulation layer 35. The reflective member 34 is covered by the light shielding layer 36 except for the intermediate portion.
Referring to fig. 3 and fig. 4 together, fig. 4 is a schematic view illustrating a first structure of a peep-proof sub-pixel area of a display panel according to a second embodiment of the application. In the embodiment of the present application, the ambient light includes visible light and ultraviolet light, and the solid arrows shown in fig. 4 are the propagation directions of the visible light, and the dotted arrows are the propagation directions of the ultraviolet light. The ambient light is transmitted to the reflective component 34 through the first light hole 36a, and the reflective component 34 reflects the ambient light to the light emitting side of the display panel 30, so that a portion of the ambient light is emitted from the light emitting side of the sub-pixel area A1, and the direction of the emitted ambient light is the direction of the large viewing angle display of the display panel 30. The light emitting side of the display panel 30 is a side of the encapsulation layer 35 facing away from the light emitting component 33, and the light emitting side of the sub-pixel area A1 is a partial area of the light emitting side of the display panel 30.
It can be appreciated that the reflection component 34 reflects the ambient light to the light emitting side of the display panel 30 (the light emitting side of the peep-proof sub-pixel area a21 and the light emitting side of the sub-pixel area A1), and the light shielding layer 36 is used for shielding the ambient light reflected by the reflection component 34 to the light shielding layer 36 due to the light shielding effect of the light shielding layer 36, the light emitting side of the peep-proof sub-pixel area a21 has no ambient light emitted, and the ambient light is emitted from the light emitting side of the sub-pixel area A1. Because the reflection assembly 34 is located in the peep-proof sub-pixel area a21, the direction of the ambient light reflected by the reflection assembly 34 to the light emitting side of the sub-pixel area A1 is the direction of displaying the display panel 30 with a large viewing angle, and when the display panel 30 is viewed from the large viewing angle, the image displayed by the display panel 30 cannot be clearly viewed, so that the display viewing angle of the display panel 30 is reduced, and the peep-proof function is realized. In addition, the reflection assembly 34 reflects the ambient light to the light emitting side of the display panel 30 without electric power driving, thereby reducing the power consumption of the display panel 30 and further reducing the use cost of the display panel 30.
In the embodiment of the application, referring to fig. 4, the reflecting component 34 includes a reflecting element 341 and a photonic crystal element 342. The reflective element 341 is disposed on a side of the light emitting component 33 opposite to the driving circuit layer 32, and is located in the peep-preventing sub-pixel area a 21. The photonic crystal element 342 is disposed on the peripheral side of the reflecting element 341 and on the side of the reflecting element 341 opposite to the light emitting component 33, that is, the reflecting element 341 is covered by the photonic crystal element 342, and the photonic crystal element 342 and the reflecting element 341 are disposed at intervals. The ambient light includes ultraviolet light and visible light, the ultraviolet light and the visible light are transmitted to the photonic crystal element 342 through the first light transmitting hole 36a, and the photonic crystal element 342 reflects most of the ultraviolet light to the light emitting side of the display panel 30. The visible light is transmitted to the reflecting element 341 through the photonic crystal element 342, and the reflecting element 341 reflects the visible light to the light emitting side of the display panel 30, so that a part of the visible light is emitted from the light emitting side of the sub-pixel area A1.
It is understood that the photonic crystal element 342 has a better reflection capability for ultraviolet light and a better transmittance for visible light, and that ultraviolet light reduces the lifetime, weather resistance, stability, etc. of the light emitting element of the display panel 30. The photonic crystal element 342 reflects most of the ultraviolet light to the light emitting side of the display panel 30, so that the display panel 30 receives less ultraviolet light, which is beneficial to improving the service life, weather resistance and stability of the display panel 30, improving the competitiveness of the display panel 30 in the market, and improving the user satisfaction and experience. Due to the light shielding effect of the light shielding layer 36, no visible light is emitted from the light emitting side of the peep-proof sub-pixel area a21, and the visible light is emitted from the light emitting side of the sub-pixel area A1. Since the reflecting element 341 is located in the peep-preventing sub-pixel area a21, the direction of the visible light reflected by the reflecting element 341 to the light emitting side of the sub-pixel area A1 is the direction of displaying the display panel 30 with a large viewing angle, and when the display panel 30 is viewed from the large viewing angle, the image displayed by the display panel 30 cannot be clearly viewed, so that the display viewing angle of the display panel 30 is reduced, and the peep-preventing function is realized.

The reflecting surface of the photonic crystal element 342 facing away from the reflecting element 341 is an arc surface, i.e., the surface of the photonic crystal element 342 reflecting the ultraviolet light is an arc surface, and the highest portion of the arc surface is aligned with the center line of the first light transmitting hole 36a, i.e., the reflecting surface of the photonic crystal element 342 protrudes toward the first light transmitting hole 36a. The height is based on the surface of the pixel layer 331 facing away from the driving circuit layer 32.
