Abstract

A spliced panel is provided. A light-emitting diode substrate is disposed on two adjacent display panels and blocks a gap. A substrate comprises a first surface, a second surface, and a third surface. The first surface and the second surface are disposed opposite to each other. The third surface is connected between the first surface and the second surface. A plurality of light-emitting diodes are disposed on the first surface. The reflective layer is disposed on the third surface. An angle between the third surface and the second surface is greater than or equal to 90°.
