For example, the encapsulation layer 600 may be stacked from multiple layers of different materials. The non-light-transmitting region may be a region corresponding to the light shielding unit 720, and when the external light is reflected by the light reduction member 400 and then emitted to the light shielding unit 720, the refractive index of the film layer is larger and the deflection angle of the light is larger as the film layer passing through the region corresponding to the light shielding unit 720 is closer to the light shielding unit 720, and the light is more perpendicular to the light shielding unit 720, so that more reflected light can be emitted to the light shielding unit 720 and be shielded and absorbed by the light shielding unit 720, thereby better reducing the reflection of the external light on the display panel 100, enhancing the contrast of the picture, and improving the display effect.
In this embodiment, in the non-transparent region, the refractive index of the same film layer is gradually decreased in a direction from the edge of the light shielding unit 720 to the center of the light shielding unit 720, specifically, referring to fig. 10, fig. 10 is a partial non-transparent region of a light shielding unit 720 corresponding to the direction from the pixel definition layer 300 to the color film layer 700, where the arrow of the dotted line in the figure is a light path diagram, and the dotted line is a separate region with different refractive indexes. When the external light is reflected by the light reduction member 400 and emitted to the light shielding unit 720, the light in the same film layer is also more and more deflected to be perpendicular to the light shielding unit 720, so that more reflected light can be emitted to the light shielding unit 720 and absorbed by the light shielding unit 720, thereby better reducing the reflection of the external light on the display panel 100, enhancing the contrast of the picture, and improving the display effect.
In this embodiment, the orthographic projection of the light-reducing member 400 on the color film layer 700 of the display panel 100 is located in the light-shielding unit 720 of the color film layer 700.

In this embodiment, the display panel 100 further includes a first organic layer 420 located between the first protrusion 410 and the anode layer, please refer to fig. 4 specifically. The first organic layer 420 is arranged to slow down the slope of the anode layer on the first protrusion 410, so that the anode layer is continuous when the anode layer film is thin, the anode layer is prevented from being abnormally broken, the effect that the convex mirror reflects external light to a non-light-transmitting area is achieved, and the normal picture display effect is ensured.
In this embodiment, the first protrusion 410 includes a plurality of first sub-protrusions 411 or/and a plurality of first sub-recesses 412, and the anode layer covers the first protrusion 410 to form an uneven convex mirror, as shown in fig. 8. The first sub-protrusions 411 or/and the first sub-recesses 412 may be increased by inert gas plasma treatment or increasing bubbles in a film before patterning the first protrusions 410.
