Abstract
A light emitting device includes a circuit board, light-emitting diodes, an optically clear adhesive layer and a transparent film. The light-emitting diodes are disposed on a surface of the circuit board. The optically clear adhesive layer is disposed on the surface of the circuit board and covers the light-emitting diodes. The transparent film is disposed over a side of the optically clear adhesive layer distant from the circuit board. A hardness of the transparent film is greater than a hardness of the optically clear adhesive layer.
