    • There is provided a light emitting device that can reduce the size of a light emitting device module by using a more simplified light emitting device that directly uses an alternating current source, prevent a decrease in luminous efficiency that is caused due to the use of a separate driving device, solve a problem with an ohmic contact of a p-type electrode, reduce the number of electrodes, and secure a larger area of light emission. A light emitting device for an alternating current source according to an aspect of the invention includes a first conductive type first semiconductor layer, a first electrode formed on the first conductive type first semiconductor layer and electrically connected to the alternating current source, a second conductive type second semiconductor layer formed on the first conductive type first semiconductor layer, a first conductive type third semiconductor layer formed on the second conductive type second semiconductor layer, and a second electrode formed on the third semiconductor layer and electrically connected to the alternating current source. Here, the light emitting device operates in response to a voltage from the alternating current source through the first electrode and the second electrode.
