Abstract: A light-emitting device, a display panel, and a display apparatus. The light-emitting device comprises a first sub-pixel region, a second sub-pixel region, and a third sub-pixel region. The light-emitting device comprises a cathode (10), an anode (30), and a light-emitting structure (20) provided between the cathode (10) and the anode (30). The light-emitting structure (20) comprises a light-emitting layer (21); and the light-emitting layer (21) comprises a single first light-emitting body (211) located in the first sub-pixel region, at least two second light-emitting bodies (212) located in the second sub-pixel region and arranged in a stacked manner, and at least two third light-emitting bodies (213) located in the third sub-pixel region and arranged in a stacked manner. The cathode (10) is used for providing electrons, and the anode (30) is used for providing holes.

Abstract: A pixel arrangement structure, a display panel, a display apparatus and a mask group are provided. The pixel arrangement structure includes: basic pixel units in first and/or second directions. Each basic pixel unit includes five sub-pixels, first to third sub-pixels are of different colors, and third to fifth sub-pixels are of a same color; the first sub-pixel includes opposite first and second sides in the first direction, and opposite third and fourth sides in the second direction; and the second sub-pixel is on and separated from the third side of the first sub-pixel, the third sub-pixel is on and separated from the first side of the first sub-pixel, fourth and fifth sub-pixels are both on the fourth side of the first sub-pixel and are separated from the fourth side of the first sub-pixel, and are separated from each other in the first direction.
