Abstract

The invention provides a display panel, a manufacturing method thereof and a display device, and relates to the technical field of display. A light emitting device layer is arranged on a driving backboard, a packaging layer, a color film layer and a light absorption layer are arranged on the side, away from the driving backboard, of the light emitting device layer, and the light absorption layer is configured to absorb light with the specific wavelength in external environment light and light emitted by the light emitting device layer; and the specific wavelength includes at least one of a wavelength between the red light band and the green light band, a wavelength between the green light band and the blue light band, and at least one of a wavelength less than the blue light band, and a wavelength greater than the red light band. The absorption layer is added in the display panel, and the light absorption layer absorbs light with a specific wavelength in external ambient light and light emitted by the light emitting device layer, so that the spectral width of the light emitted from the light emitting surface of the display panel is narrowed, and the color purity of the light emitted from the light emitting surface of the display panel is improved; therefore, the display effect 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, a manufacturing method thereof, and a display device. Background technique

[0002] With the continuous development of display technology, OLED (Organic Light Emitting Diode, Organic Light Emitting Diode) display panel has been widely concerned due to its advantages of low energy consumption, low production cost, self-illumination, wide viewing angle and fast response speed. .

[0003] However, at present, the color purity of the light emitted from the light emitting surface of the display panel is not high, resulting in poor display effect of the display panel, and the problem of color shift easily occurs at certain angles. Contents of the invention

[0004] The present invention provides a display panel, a manufacturing method thereof, and a display device to solve the problem that the color purity of the light emitted from the light-emitting surfac...
