Abstract

A light board and a carrying device thereof are provided. The light board includes a substrate and at least one support pin. The carrying device includes a plurality of carrying plates, and each carrying plate is used for carrying a light board. Every adjacent carrying plate and light board serve as a group of packaging structure. Each carrying plate is provided with a plurality of plate avoidance holes therein, and each substrate is provided with a plurality of substrate avoidance holes therein. In the group of packaging structure, at least one plate avoidance hole and at least one substrate avoidance hole are corresponding and serve as a avoidance hole group, and a support pin of a light board in a group of packaging structure located below passes through an avoidance hole group in at least one group of packaging structure located above.
