Display panel and display device

A display panel, comprising:

• a plurality of pixel units arranged in a row direction and a column direction, wherein the display panel comprises a display region,
• an edge of the display region comprises a fold line formed by connecting a line segment extending in the row direction and a line segment extending in the column direction,
• a parallelogram region formed in the display region taking two adjacent line segments as adjacent sides comprises a plurality of rows and at least one column of the pixel units, or at least one row and a plurality of columns of the pixel units, and
• a direction from an intersection point of the two adjacent line segments to an end point of one of the two adjacent line segments other than the intersection point is a first direction, a direction from the intersection point of the adjacent two line segments to an end point of the other one of the two adjacent line segments other than the intersection point is a second direction;
• in the parallelogram region, aperture ratios of the pixel units arranged in at least one selected from the group consisting of the first direction and the second direction increase gradually,
• wherein each of the pixel units comprises a plurality sub-pixels of multiple colors arranged in the row direction, and in the parallelogram region, each sub-pixel in each of the pixel units has a same aperture ratio;
• a light-shading layer is between adjacent ones of the pixel units, and a material of the light-shading structure is the same as a material of the light-shading layer;
• each of the pixel units in the parallelogram region comprises a light-shading structure, and light-shading areas of light-shading structures of the pixel units arranged in at least one selected from the group consisting of the first direction and the second direction decrease gradually, so that the aperture ratios increase gradually;
• and wherein the light-shading structure comprises at least one sub light-shading structure extending in the column direction, the light-shading layer comprises a plurality of sub light-shading layers extended in the column direction, and the sub light-shading structure has a same shape and a same size as one of the plurality of sub light-shading layers.
