Abstract
A substrate includes a circuit board and a first reflective layer. The first reflective layer is disposed on the substrate. The first reflective layer has a central region and a peripheral region surrounding the central region. The first reflective layer includes at least one first buffer structure group, and an orthogonal projection of the first buffer structure group on the circuit board falls into the peripheral region. Each first barrier structure group includes a plurality of first slits spaced apart from each other, and a plurality of first slits in any first buffer structure group are disposed around the central region.
