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 θ2 and an azimuth angle of Φ2, and a ratio of the second intensity to the first intensity is less than or equal to 0.1, wherein θ2 ranges from 35° to 55°, and Φ2 ranges from 0° to 28° or from 152° to 180°.
