Transparent display panel and display device with adjacent subpixels of same color arrangement

A display device, comprising a display panel comprising a plurality of pixel units disposed along a first direction and a second direction, wherein:

• a pixel unit of the plurality of pixel units includes at least three subpixels with different colors;
• in a same pixel unit, at least two of the subpixels are disposed along a first direction, along a second direction, at least one of the subpixels is on a side of the two subpixels disposed along the first direction, and the first direction intersects the second direction;
• in two pixel units that are at least partially adjacent, a subpixel in one of the two pixel units is adjacent to a subpixel in the other one of the two pixel units, and colors of the two adjacent subpixels are same;
• each of the at least three subpixels includes a light-emitting layer, and a cathode electrode block and an anode electrode block on two sides of the light-emitting layer along a direction perpendicular to a plane where the display panel is located;
• and
• the display panel includes a plurality of cathode electrode blocks that are patterned as discrete cathode islands on a cathode layer, and in two adjacent pixel units, at least two adjacent subpixels with a same color share a same cathode electrode block.
