Further, the planarization layer 105 is disposed on the electrode layer 104, and at the same time, the planarization layer 105 completely covers the electrode layer 104.
In the embodiment of the present invention, the substrate 101 may be configured as a multi-layer stacked structure, such as a stacked structure of an organic layer and an inorganic layer, so as to improve the supporting and buffering effects of the substrate on other layers.

Specifically, the black matrix layer 107 may include a plurality of open regions and light-shielding regions. The opening region may be a pixel opening, and the light-shielding region may correspond to a light-shielding portion of the black matrix layer 107. Light can be transmitted from the opening area of each pixel but not in the light shielding area.
In the embodiment of the present application, the pixel openings are exemplified by the first pixel opening 31, the second pixel opening 32 and the third pixel opening 33 which are arranged in a patterning manner, and a light shielding region is arranged between two adjacent pixel openings.
Furthermore, the display panel further comprises a color resistor, and the color resistor is correspondingly arranged in each pixel opening. Wherein the color resistance comprises a plurality of color resistances of different colors. In the embodiment of the present application, the color resistors are exemplified by the first color resistor 211, the second color resistor 212, and the third color resistor 213.

The color resistances of two colors or the color resistances of three colors can be set, specifically, the color resistances are set according to the corresponding light-emitting pixels of the actual product, and are not described herein again.
In the following embodiments, the first color resistor 211 is a green resistor, the second color resistor 212 is a blue resistor, and the third color resistor 213 is a red resistor.

Thus, the filling portion 2112 is higher than the black matrix layer 107 by a certain height, and when light is transmitted through the filling portion 2112, the light can be transmitted to the maximum extent, thereby increasing the transmittance of the light.
Meanwhile, the protrusion 2111 is connected to the filling portion 2112, and the protrusion 2111 is disposed above the filling portion 2112, so that when light is emitted from the light emitting layer 110, the light sequentially passes through the respective layers, enters the region corresponding to the first pixel opening 31, sequentially passes through the filling portion 2112 and the protrusion 2111, and passes out of the first color resist 211.
In the embodiment, when the protrusion portion 2111 is provided, the protrusion portion 2111 may be provided as an arc protrusion, a spherical protrusion, or the like. In the following embodiment, the case where the convex portion 2111 is provided as a spherical protrusion will be described.
Wherein, the convex direction of the spherical convex is the same as the emergent light direction of the light-emitting layer 110. And the surface of the spherical bulge is a gently-transitional bulge surface.
In the embodiment of the present application, the height between the protrusion 2111 and the upper surface of the black matrix layer 107 is H1, wherein the height of H1 can be set to 1.0um-2.0um, and preferably, the height H1 is set to 1.8um.

Further, the protrusion 2111 may be configured as a convex mirror structure with other shapes, such as an arch structure, which is not described herein. One end of the first color resistor 211 is set to be a convex lens structure, so that the emergent effect of the light is effectively improved.
In the embodiment of the present application, when the second color resistor 212 and the third color resistor 213 are disposed, the blue color resistor corresponding to the second color resistor 212 and the red color resistor corresponding to the third color resistor 213 can be disposed in the same structure, such as a planar structure. That is, the upper surfaces of the second color resistor 212 and the third color resistor 213 are disposed in a horizontal plane structure, and the horizontal plane can be parallel to the upper surface of the black matrix 107.
Specifically, when the second color resistor 212 and the third color resistor 213 are disposed, the second color resistor 212 is correspondingly disposed in the second pixel opening 32, and the third color resistor 213 is correspondingly disposed in the third pixel opening 33. And when it is set, the height of the second color resistor 212 and the third color resistor 213 is larger than the thickness of the black matrix layer 107.
In the embodiment of the present application, the height of the second color resists 212 and the third color resists 213 beyond the upper surface of the black matrix layer 107 is H2, and specifically, the height H2 is set to be 1.5um to 2.0um. Preferably, the height H2 is set to 1.6um.
Specifically, the widths of the second color resistor 212 and the third color resistor 213 are both greater than the opening diameter of the corresponding pixel opening. Thereby the effect of the color resistance of different colors on light is effectively ensured.
Meanwhile, the height of the first color resistor 211 can be larger than the second color resistor 212 and the third color resistor 213. In the embodiment of the present application, when the pixel openings corresponding to the color resistors of different colors are arranged, the sizes of the color resistors corresponding to different colors are different. Specifically, the opening radius of the first pixel opening 31 corresponding to the first color resistor 211 is smaller than the opening radius of the third pixel opening 33 corresponding to the third color resistor 213, and the opening radius of the third pixel opening 33 corresponding to the third color resistor 213 is smaller than the opening radius of the second pixel opening 32 corresponding to the second color resistor 212.

Further, the display panel further includes a metal trace 106 and a first photoresist 108. The metal trace 106 is disposed on the planarization layer 105, and the metal trace 106 is disposed at a light-shielding region corresponding to the black matrix layer 107. The black matrix layer 107 completely covers the metal trace 106.
Meanwhile, the first photoresist 108 is disposed on the black matrix layer 107, and the first photoresist 108 completely covers the color resists.
In the embodiment of the present application, the light refractive index of the first photoresist 108 is greater than the light refractive index corresponding to the color resistance. Specifically, the light refractive index of the first photoresist 108 is greater than the light refractive index of the first color resist 211. Meanwhile, the light refractive index of the first photoresist 108 may also be larger than the light refractive index corresponding to the second color resist 212 and the third color resist. Thus, after the light sequentially passes through the first color resistor 211 and the first photoresist 108, the light emitting effect in the first color resistor 211 is effectively improved. Thereby improving the display effect in the first display area.
Specifically, the refractive index of the first photoresist 108 is set to 1.4-1.5, and the refractive index of the first color photoresist 211 is set to 1.6-1.7. Preferably, the light refractive index of the first photoresist 108 is set to 1.4, and the light refractive index of the first color resist 211 is set to 1.65.
