Abstract
A display panel includes a pixel array layer and a light-blocking layer. The pixel array layer has a plurality of pixel blocks, and each pixel block has a first side. The light-blocking layer disposed above the pixel array layer and has a plurality of first light-blocking belts corresponding to the pixel blocks. The first light-blocking belt at least partially extends along the first side of its corresponding pixel block. Accordingly, the outgoing light emitted at a larger angle from the pixel blocks can be at least partially blocked.

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°−D1)/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°+D0)/W≥70%
- wherein:
- D1:
- 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;
- D0:
- 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.
