A light emitting device is switchable in a first state and a second state. The light emitting device includes a plurality of light emitting elements for emitting lights and an optical element. The optical element is configured to guide the emitting lights generating from the light emitting elements. In the first state, the light emitting device has an output light, a first intensity of the output lights is measured at a viewing angle of 0°, a second intensity of the output lights is measured at a viewing angle of θand an azimuth angle of Φ, and a ratio of the second intensity to the first intensity is less than or equal to 0.1, wherein θranges from 35° to 55°, and Φranges from 0° to 28° or from 152° to 180°.
