among them, in part or all of the plurality of light emitting units 111, a light emitting unit optical isolation structure 300 is disposed between two adjacent light emitting units 111.

In this way, the light-emitting unit optical isolation structure 300 can prevent light emitted from two adjacent light-emitting units 111 from being transmitted in an undesired direction (for example, light emitted from two adjacent light-emitting units 111 is transmitted to each other) as much as possible, which is advantageous for improving display effect.

Referring to fig. 2A, 2B, and 2C, in some embodiments, the light emitting cell optical isolation structure 300 may be disposed at a partial or entire region between two adjacent light emitting cells 111.

In some embodiments, as shown in fig. 2A, the light-emitting unit optical isolation structure 300 is disposed at a partial region between two adjacent light-emitting units 111, the partial region being located between the two adjacent light-emitting units 111 and near one of the light-emitting units 111 (the light-emitting unit 111 located on the left side in the figure).

In some embodiments, as shown in fig. 2B, the light-emitting unit optical isolation structure 300 is disposed in a partial region between two adjacent light-emitting units 111, the partial region being located between the two adjacent light-emitting units 111 and opposite to the position where the light-emitting unit optical isolation structure 300 is located in fig. 2A (close to the light-emitting unit 111 located on the right side in the figure).
