Abstract

The invention discloses a display panel and a display device. The display panel comprises light-emitting elements, and the light-emitting elements comprise a first light-emitting element emitting first color light rays with the wavelength range of lambda1-lambda2, a second light-emitting element emitting second color light rays with the wavelength range of lambda3-lambda4, and a third light-emitting element emitting third color light rays with the wavelength range of lambda5-lambda6. The display panel also comprises cover cap layers which covers light-emitting sides of the light-emitting elements, wherein the first light-emitting element comprises a first cover cap layer, the second light-emitting element comprises a second cover cap layer, and the third light-emitting element comprises athird cover cap layer. At least one of the first cap layer, the second cap layer and the third cap layer contains an ultraviolet light absorber, and the absorptivity A(380nm-410nm) of the ultravioletlight absorber for the light rays in the wavelength range of 380nm-410nm is greater than or equal to 20%. According to the display panel, irradiation of ultraviolet light on a phosphorescent materialcan be reduced, high-energy light is prevented from irradiating human eyes, and therefore better user experience is provided while the performance of the display panel is improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display panel and a display device including the display panel. Background technique [0002] With the continuous development of display technology, consumers' requirements for display panels continue to increase, and various display panels emerge in an endless stream, and have been developed rapidly, such as liquid crystal display panels, organic light-emitting displays and other display panels. In the world, display technologies such as 3D display, touch display technology, curved surface display, ultra-high resolution display, and anti-peep display are constantly emerging to meet the needs of consumers. [0003] Organic light-emitting display panels are widely favored by consumers because of their advantages such as light and thin, easy to bend, high contrast, and low power consumption. Its market share in the display field is increasing year by year, and it is curr...
