In the embodiment of the present application, the first electrode layer 21 is a cathode layer, the cathode layer has a capability of reflecting light, and the cathode layer has a certain light transmittance, the thinner the cathode layer is, the stronger the light transmittance is, the thicker the cathode layer is, and the weaker the light transmittance is. In the embodiment of the present application, the display panel further includes an anode layer 23 on the substrate 60, the light emitting function layer 20 is on the anode layer 23, and the cathode layer is on the light emitting function layer 20. In the embodiment of the present application, the cathode layer has a certain light transmittance, so that the light emitted from the light emitting functional layer 20 can be emitted along the cathode layer in the pixel opening 11. In the embodiment of the present application, the cathode layer covers the pixel definition structures 12 on the light emitting side of the display panel of the pixel definition layer 10 at the same time, so as to reduce or improve the output of the light of the display panel through the top (light emitting side of the display surface) of the pixel definition structures 12 between the pixel openings 11 in the first region 30, reduce or improve the output of the light of the display panel through the top (light emitting side of the display surface) of the pixel definition structures 12 between the pixel openings 11 in the second region 40, and improve the occurrence of color mixing of the display panel. In the embodiment of the present application, when the cathode layer is manufactured, the cathode layer covers the light emitting functional layer 20 in the pixel opening 11, and the cathode layer covers the pixel definition structure 12 of the first electrode layer 21 on the light emitting side of the display panel in the second region 40 and the first region 30, so that the effect of improving the color mixing of the display panel can be achieved, and the manufacturing steps are not increased. In the embodiment of the present application, the cathode layer may be made of Mg: in other embodiments, the cathode layer may be made of Al. In other embodiments, a portion of the first electrode layer 21 may be located in the pixel opening 11, and the remaining first electrode layer 21 is located on the first pixel defining structure 121, so as to reduce the amount of light emitted from a position between the first region 30 and the second region 40.

When the materials of the light reflecting layer 50 and the first electrode layer 21 are the same, the thickness of the cathode layer on the first pixel defining structure 121 is made to be greater than the thickness of the cathode layer on the second pixel defining structure 122, and by increasing the thickness of the cathode layer on the first pixel defining structure 121, the light transmission amount of the cathode layer on the first pixel defining structure 121 can be reduced, the amount of the transverse transmission light per unit area of the first pixel defining structure 121 is increased, so that the amount of the light transmitted from the second region 40 to the first region 30 is increased, and the light intensity in the pixel opening 11 of the first region 30 close to the second region 40 is increased. In the embodiment of the application, the material of the reflective layer 50 is the same as that of the first electrode layer 21, so that when the display panel is manufactured, the evaporation chamber does not need to be replaced when the reflective layer 50 and the first electrode layer 21 are manufactured by evaporation, the manufacturing time of the display panel is saved, and the cost of production line equipment for manufacturing the display panel is not increased. In the embodiment of the present application, when the cathode layer is manufactured, after the light emitting functional layer 20 is manufactured in the pixel opening 11 of the pixel defining layer 10, a cathode layer is manufactured, so that the cathode layer covers the pixel defining layer 10 and the light emitting functional layer 20 in the pixel opening 11; then, a cathode layer is formed on the first pixel defining structure 121 by using a mask, so that the thickness of the cathode layer on the first pixel defining structure 121 is greater than that of the cathode layer on the second pixel defining structure 122. In another embodiment, a cathode layer may be formed on the first pixel defining structure 121 by using a mask, and then a cathode layer may be formed on the pixel defining layer 10 and the light emitting functional layer 20 in the pixel opening 11. So that the thickness of the cathode layer on the first pixel defining structure 121 is greater than that on the second pixel defining structure 122. In the embodiment of the present application, the reflective layer 50 and the first electrode layer 21 are both made of Mg: in other embodiments, the reflective layer 50 and the first electrode layer 21 may be made of Al. In other embodiments, the light reflecting layer 50 and the first electrode layer 21 may be made of different materials, for example, the light reflecting layer 50 is made of Ag, and the first electrode layer 21 is made of Al.

The jagged display picture caused by the fact that the second area 40 is displayed too bright and the first area 30 is displayed too dark is greatly improved, and the display transition between the first area 30 and the second area 40 is natural.
In the embodiment of the present application, the light emitting color of the adjacent light emitting functional layer 20 on one side of the light guide structure is the same as the light emitting color of the adjacent light emitting functional layer 20 on the other side of the light guide structure, that is, the light emitting color of the adjacent light emitting functional layer 20 on one side of the first pixel defining structure 121 is the same as the light emitting color of the adjacent light emitting functional layer 20 on the other side of the first pixel defining structure 121. By arranging the light emitting color of the light emitting function layer 20 on the two sides of the first pixel defining structure 121 to be the same, when the light of the light emitting function layer 20 in the pixel opening 11 of the second region 40 is transmitted into the pixel opening 11 of the first region 30, the light intensity in the pixel opening 11 of the first region 30 can be enhanced, and the display cross color of the display panel can be reduced.
