In some other specific implementation, as shown in FIG. 7, the light-emitting layer of at least one color may further include a third color light-emitting layer 43, and the third color light-emitting layer 43 includes a plurality of third main body parts 431 in the display region 11 and third virtual parts 432 in the virtual pixel region 121. One first main body part 411 or one second main body part 421 is included between two adjacent third main body parts 431, thus it can be considered that in the second direction X, the first main body parts 411 and the second main body parts 421 are arranged alternately, and one third main body part 431 is disposed between the adjacent first main body part 411 and second main body part 421. In the second direction, the third virtual parts 432 are arranged alternately in the first virtual pixel region 121a and the second virtual pixel region 121b.

Specifically, as shown in FIG. 7, the first color light-emitting layer 41, the second color light-emitting layer 42 and the third color light-emitting layer 43 respectively correspond to a red organic light-emitting layer, a green organic light-emitting layer and a blue organic light-emitting layer. In the present embodiments, the quantity of the main body parts of the blue organic light-emitting layer is greater than the quantity of the main body parts of the red organic light-emitting layer, and greater than the quantity of the main body parts of the green organic light-emitting layer, thereby advantageously compensating the light-emitting efficiency of the blue light-emitting material and improving the service life of the display apparatus.
