Display panel

1. A display panel, comprising:

a pixel array layer having a plurality of pixel blocks, each of the pixel blocks having a first side;

a light-blocking layer disposed above the pixel array layer, the light-blocking layer having a plurality of first light-blocking belts corresponding to the pixel blocks, each of the first light-blocking belts at least partially extending along the first side of its corresponding pixel block;

wherein when a vertical projection of the first light-blocking belt on the pixel array layer does not overlap the first side of its corresponding pixel block, the following equation exists:

( H ×tan 30°− D 1 )/ W≥ 70%

wherein when the vertical projection of the first light-blocking belt on the pixel array layer overlaps the first side of its corresponding pixel block, the following equation exists:

( H ×tan 30°+ D 0 )/ W≥ 70%

wherein:

D 1 : a distance between the vertical projection of the first light-blocking belt on the pixel array layer and the first side of its corresponding pixel block in a direction perpendicular to the first side;

D 0 : a width of an overlapping area of the vertical projection of the first light-blocking belt on the pixel array layer and the pixel block in the direction perpendicular to the first side;

H: a distance between the first light-blocking belt and its corresponding pixel block in a direction perpendicular to the pixel array layer; and

W: a width of the pixel block in the direction perpendicular to the first side.

2. The display panel of claim 1 , wherein the pixel block has an extending direction; the extending direction is substantially parallel to an extending direction of the first side.

3. The display panel of claim 1 , wherein the pixel block has a second side opposite to the first side; a distance D 2 is between the second side and the vertical projection of a closest first light-blocking belt on the pixel array layer in a direction perpendicular to the second side; D 2 is larger than D 1 .

4. The display panel of claim 1 , wherein the pixel block has a third side substantially perpendicular to the first side; the light-blocking layer has a plurality of second light-blocking belts respectively corresponding to the pixel blocks; each of the second light-blocking belts at least partially extends along the third side of its corresponding pixel block; a distance D 3 is between the third side and the vertical projection of its corresponding second light-blocking belt on the pixel array layer in a direction perpendicular to the third side; D 3 is larger than D 1 .

5. The display panel of claim 1 , wherein the light-blocking layer has a plurality of color filtering blocks distributed between the first light-blocking belts, vertical projections of the color filtering blocks on the pixel array layer at least partially overlap the pixel blocks, respectively.

6. The display panel of claim 5 , wherein a width of the vertical projection of each of the color filtering blocks on the pixel array layer is larger than a width of its corresponding pixel block in the direction perpendicular to the first side.

7. The display panel of claim 1 , wherein the pixel block is formed by a self-luminous light source.

8. The display panel of claim 1 , wherein the pixel array layer is disposed on a first substrate; the light-blocking layer is disposed on a second substrate; at least one of the first substrate and the second substrate has an alignment mark for alignment of the first substrate and the second substrate.

9. The display panel of claim 1 , wherein at least a portion of the pixel blocks are arranged side by side along a direction parallel to the first side and correspond to a same first light-blocking belt.
