An electronic device that includes a light-emitting board and a light characteristics enhancing member. The light-emitting board includes a driving substrate, a semiconductor device disposed on a first surface of the driving substrate, and a signal-receiving member receiving an external wireless control signal to control the semiconductor device. The light characteristics enhancing member includes a base film disposed over the light-emitting board, and a light characteristics enhancing layer formed on a lower surface of the base film, the lower surface facing the light-emitting board. A second refractive index of the light characteristics enhancing layer is greater than a first refractive index of the base film. Therefore, the receive sensitivity of the external wireless control signal is improved.
