Abstract
A light emitting device includes a plurality of light emitting elements emitting lights and a light controller. The light controller is disposed on the light emitting elements for the lights passing through to form output lights, which is switchable in a first state and a second state. In the first state, a first intensity 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°.
