Array substrate and display device

A display device, comprising:

• an array substrate, comprising:
• a first substrate;
• and
• a plurality of sub-pixel structures disposed on the first substrate, wherein the sub-pixel structures comprise:
• a first sub-pixel structure having a first center and comprising a first reflecting region and at least one first penetrating region;
• a second sub-pixel structure having a second center and comprising a second reflecting region;
• and
• a third sub-pixel structure having a third center and comprising a third reflecting region;
• an opposite substrate opposite to the array substrate;
• and
• a display medium layer disposed between the array substrate and the opposite substrate;
• wherein the first sub-pixel structure, the second sub-pixel structure and the third sub-pixel structure are adjacent to each other and display different colors, and the first center, the second center and the third center are three vertices of a triangle;
• wherein at least two of a geometric shape of the first sub-pixel structure, a geometric shape of the first reflecting region and a geometric shape of the first penetrating region are not quadrilaterals.
