Display panel and display device

A display panel comprising a first substrate, the first substrate comprising:

• a plurality of pixels;
• each of the plurality of pixels comprises a plurality of sub-pixels of different colors, and wherein the sub-pixels of each of the different colors comprise a first sub-pixel and a second sub-pixel;
• wherein first sub-pixel comprises a first sub-pixel electrode, which comprises a first trunk that divides the first sub-pixel electrode into a plurality of alignment domains, and a plurality of first branches that are uniformly arranged in the alignment domains of the first sub-pixel electrode;
• wherein the second sub-pixel comprises a second sub-pixel electrode, which comprises a second trunk that divides the second sub-pixel electrode into a plurality of alignment domains, and a plurality of second branches that are uniformly arranged in the alignment domains of the second sub-pixel electrode;
• wherein the first trunk comprises a first horizontal trunk disposed in a middle of a vertical direction of the first sub-pixel electrode, a first vertical trunk disposed in a middle of a horizontal direction of the first sub-pixel electrode, and a plurality of first branches that are uniformly arranged in the alignment domains of the first sub-pixel electrode, wherein the first horizontal trunk and the first vertical trunk divide the first sub-pixel electrode into four alignment domains;
• wherein the second trunk comprises a second horizontal trunk disposed in a middle of a vertical direction of the second sub-pixel electrode, a second vertical trunk disposed in a middle of a horizontal direction of the second sub-pixel electrode, and a plurality of second branches that are uniformly arranged in the alignment domains of the second sub-pixel electrode, wherein the second horizontal trunk and the second vertical trunk divide the second sub-pixel electrode into four alignment domains;
• wherein the first horizontal trunk has a greater width than that of the second horizontal trunk, the first vertical trunk has a greater width than that of the second vertical trunk, and wherein a ratio of a horizontal projection area of the first trunk to a total area of the first sub-pixel electrode is greater than a ratio of a horizontal projection area of the second trunk to a total area of the second sub-pixel electrode.

A display device comprising a display panel, the display panel comprising a first substrate, the first substrate comprising:

• a plurality of pixels;
• wherein each of the plurality of pixels comprises a plurality of sub-pixels of different colors;
• wherein the sub-pixels of each of the different colors comprise a first sub-pixel and a second sub-pixel;
• wherein the first sub-pixel has a smaller aperture ratio than that of the second sub-pixel.
