1. A light emitting device for a display, comprising:
a first LED laterally extending along a first direction and including a first n-type layer, a first active layer, and a first p-type layer;
a second LED including a second n-type layer, a second active layer, and a second p-type layer;
a third LED including a third n-type layer, a third active layer, and a third p-type layer;
electrodes disposed under the first LED, each of the electrodes overlapping at least a portion of the first LED along a vertical direction and being electrically connected to at least one of the first LED, the second LED, and the third LED;
an insulator disposed under the electrodes and having a first surface extending in the first direction;
a mold having an outer boundary and covering each of the first LED, the second LED, and the third LED; and
leads electrically connected to the electrodes, each of the leads extending along the first surface and a side surface of the insulator,
wherein the leads include a common lead electrically connected to each of the first LED, the second LED, and the third LED in common, and individual leads electrically connected to the first LED, the second LED, and the third LED, respectively,
wherein the common lead and one of the individual leads near a center of the light emitting device are spaced apart in the first direction by a first distance, and the common lead and the one of the individual leads near an outer side of the light emitting device are spaced apart in the first direction by a second distance greater than the first distance in plan view, and
wherein the insulator includes a first region disposed between one of the leads and the first LED, and a second region disposed between the one of the leads and the mold along the vertical direction, wherein the second region extends outward of the first LED from the first region.
