Abstract

Provided are a display panel and a display device. The display panel includes a base substrate, an anode layer disposed on the base substrate, a pixel defining layer located on a side of the anode layer facing away from the base substrate and including first openings, a light-emitting layer located in each of the plurality of first openings, and a black matrix located on a side of the light-emitting layer facing away from the base substrate and including second openings; where the orthographic projection of each of the plurality of first openings on the base substrate overlaps the orthographic projection of each of the plurality of second openings on the base substrate, the plurality of second openings includes first-type openings, and each first-type opening of the plurality of first-type openings is polygonal and includes at least one first-type edge.

Claims (35)

1 . A display panel, comprising:

a base substrate and an anode layer disposed on the base substrate;

a pixel defining layer located on a side of the anode layer facing away from the base substrate, wherein the pixel defining layer comprises a plurality of first openings;

a light-emitting layer corresponding to the plurality of first openings; and

a black matrix located on a side of the light-emitting layer facing away from the base substrate, wherein the black matrix comprises a plurality of second openings;

wherein an orthographic projection of the first opening overlaps an orthographic projection of a second opening of the plurality of second openings; the plurality of second openings comprises a plurality of first-type openings,

wherein each first-type opening of the plurality of first-type openings is polygonal and comprises at least one first-type edge and each first-type opening corresponds to a pixel having a single opening structure, wherein the at least one first-type edge and the plurality of first openings comprise the following relationship: each first-type edge of the at least one first-type edge is not parallel to a direction in which the plurality of first openings are arranged,

wherein the plurality of second openings further comprises a plurality of second-type openings, and a shape of a second-type opening of the plurality of second-type openings is same as a shape of the first opening corresponding to the second-type opening; and

the light-emitting layer comprises red light-emitting blocks, green light-emitting blocks, and blue light-emitting blocks, and second openings of the plurality of second openings corresponding to at least part of the blue light-emitting blocks are the second-type openings, and second openings of the plurality of second openings corresponding to at least part of the green light-emitting blocks or second openings of the plurality of second openings corresponding to at least part of the red light-emitting blocks are the first-type openings.

2 . The display panel of claim 1 , wherein

the light-emitting layer comprises red light-emitting blocks, green light-emitting blocks, and blue light-emitting blocks, and at least one second opening of the plurality of second openings corresponding to the green light-emitting blocks is the first-type opening.

3 . The display panel of claim 1 , wherein

the first-type opening is formed by the first-type edge.

4 . The display panel of claim 1 , wherein

the first-type opening further comprises at least one second-type edge, and one of the at least one second-type edge in the first-type opening is parallel to an edge of the first opening, wherein the first-type opening corresponds to the first opening, and the one of the at least one second-type edge neighbors the edge of the first opening.

5 . The display panel of claim 1 , wherein

the at least one first-type edge is a linear segment.

6 . A display panel, comprising:

a base substrate and an anode layer disposed on the base substrate;

a pixel defining layer located on a side of the anode layer facing away from the base substrate, wherein the pixel defining layer comprises a plurality of first openings;

a light-emitting layer corresponding to the plurality of first openings; and

a black matrix located on a side of the light-emitting layer facing away from the base substrate, wherein the black matrix comprises a plurality of second openings;

wherein an orthographic projection of the first opening overlaps an orthographic projection of a second opening of the plurality of second openings; the plurality of second openings comprises a plurality of first-type openings,

wherein each first-type opening of the plurality of first-type openings is polygonal and comprises at least one first-type edge and each first-type opening corresponds to a pixel having a single opening structure, wherein the at least one first-type edge and the plurality of first openings comprise at least one of the following relationship: each first-type edge of the at least one first-type edge is not parallel to a direction in which the plurality of first openings are arranged, wherein extension directions of the at least one first-type edge in a same first opening are different from each other.

7 . A display device, comprising:

a display panel, wherein display panel comprises:

a base substrate and an anode layer disposed on the base substrate;

a pixel defining layer located on a side of the anode layer facing away from the base substrate, wherein the pixel defining layer comprises a plurality of first openings;

a light-emitting layer corresponding to the plurality of first openings; and

a black matrix located on a side of the light-emitting layer facing away from the base substrate, wherein the black matrix comprises a plurality of second openings;

wherein an orthographic projection of the first opening overlaps an orthographic projection of a second opening of the plurality of second openings;

the plurality of second openings comprises a plurality of first-type openings, wherein each first-type opening of the plurality of first-type openings is polygonal and comprises at least one first-type edge and each first-type opening corresponds to a pixel having a single opening structure, wherein the at least one first-type edge and the plurality of first openings comprise at least one of the following relationship:

each first-type edge of the at least one first-type edge is not parallel to a direction in which the plurality of first openings are arranged,

wherein the plurality of second openings further comprises a plurality of second-type openings, and a shape of a second-type opening of the plurality of second-type openings is same as a shape of the first opening corresponding to the second-type opening; and

the light-emitting layer comprises red light-emitting blocks, green light-emitting blocks, and blue light-emitting blocks, and second openings of the plurality of second openings corresponding to at least part of the blue light-emitting blocks are the second-type openings, and second openings of the plurality of second openings corresponding to at least part of the green light-emitting blocks or second openings of the plurality of second openings corresponding to at least part of the red light-emitting blocks are the first-type openings.
