The examples are not to be construed as limiting the specific techniques or conditions described in the literature in this field or as per the specifications of the product. The reagents or apparatus used were conventional products commercially available without the manufacturer's attention.

In one aspect of the present invention, a display panel 1 is proposed, referring to fig. 1, the display panel 1 comprising: a substrate 11, a pixel defining layer 12, a plurality of light emitting devices 13, a reflective layer 14, and a color film layer 15.

Wherein the pixel defining layer 12 defines a plurality of openings; the effective light emitting area of the light emitting device 13 is located in the opening; the reflective layer 14 is disposed on a side of the pixel defining layer 12 remote from the substrate 11, the reflective layer 14 satisfying at least one of the following conditions: the reflectivity of the reflective layer 14 is 1% -10%; the light transmittance of the reflective layer 14 is 50% -90%; the color film layer 15 is disposed on a side of the reflective layer 14 away from the substrate 11, and there is no overlapping area between the front projection of the color film layer 15 on the substrate 11 and the opening, and there is an overlapping area between the front projection of the color film layer 15 on the substrate 11 and the front projection of the reflective layer 14 on the substrate 11. Therefore, the display panel 1 can display color in the screen-off state, and the color film is set to be the same color as the appearance of the display panel 1, so that the whole appearance of the display panel 1 in the screen-off state can be always kept, and the aesthetic feeling is improved.

The principle of the present invention capable of achieving the above advantageous effects will be described in detail as follows:

the display panel 1 is provided with the reflecting layer 14, one side of the reflecting layer 14, which is away from the substrate 11, is provided with the color film, when the reflectivity of the reflecting layer 14 is 1% -10%, natural light irradiates the reflecting layer 14 in a screen-off state, light rays are reflected, the reflected light rays irradiate the color film, and colors are displayed through the color film; when the light transmittance of the reflective layer 14 is 50% -90%, compared with the display panel 1 with higher light transmittance (about 99.9%), the natural light can be reflected when being irradiated onto the reflective layer 14, the reflected light can be irradiated onto the color film, the color is displayed through the color film, and the color film is set to be the same as the appearance of the display panel 1, so that the whole appearance of the display panel 1 is kept consistent in the screen-off state, and the aesthetic feeling of the display panel 1 is improved. Because the color film does not cover the light emitting device 13, the light emitted by the light emitting device 13 does not need to pass through the color film layer 15, so that the color film layer 15 can be prevented from influencing the light emitting effect when the display panel 1 is in a display state, the display effect is improved, the light emitting efficiency of the display panel 1 is improved, and the power consumption of the display panel 1 is reduced.

Therefore, natural light can be reflected to the color film in the screen-off state, and light emitted by the light-emitting device 13 does not pass through the reflecting layer 14 in the display state, so that the light-emitting efficiency of the display panel 1 can be improved, and the power consumption of the display panel 1 can be reduced.
