For products such as a display, a notebook and the like, peeping is difficult in the up-down direction, and the peeping prevention effect is usually good only in the left-right direction. In this embodiment, the first light-emitting region 3322, the hollow region 3321 and the second light-emitting region 3323 are arranged in the row direction, so that the display panel has better anti-peeping effect in the left-right direction, and meanwhile, the size of the hollow region 3321 can be enlarged to the greatest extent, the consumption of organic light-emitting materials is reduced, and the manufacturing cost of the display panel is reduced.

Light-emitting gaps are formed between the periphery of the light-shielding unit 361 and the black matrix and the color resistors, so that the peep-proof light-emitting part 332 can emit light from the periphery of the light-shielding unit 361 conveniently. An anti-reflection layer 380 is formed on the side of the color resist layer 370 remote from the substrate 100.
In order to improve the contrast ratio of the display device and realize an integral black effect, the OLED display panel generally adopts a polarizer, which can effectively reduce the reflection intensity of external ambient light on a screen. However, the light transmittance of the polarizer is generally only about 44%, and more power consumption is required to achieve higher light-emitting brightness. In addition, the polaroid has larger thickness and crisp material, and is not beneficial to the development of dynamic bending products.
The display panel in this embodiment includes an anti-reflection layer 380, where the anti-reflection layer 380 can reduce the reflection intensity of the external ambient light on the screen. In addition, the anti-reflection layer 380 also has a certain blocking effect, so that the OLED display panel can be protected. The reflection intensity of external environment light on a screen is reduced by adopting the anti-reflection layer 380, external light is blocked by adopting the color resistance layer 370, and the light emitted by the display light-emitting unit is filtered, so that the polaroid of the OLED display panel can be eliminated, the thickness of the functional layer is greatly reduced, the light emitting rate is improved from 44% to 80%, the light emitting brightness is greatly increased, and the power consumption of the OLED display panel is reduced.
