1. A light-emitting display device, comprising:
a display panel in which a plurality of active areas including a first active area and a second active area is defined;
a plurality of sub-pixels disposed in each of the plurality of active areas; and
a gate driver disposed on the plurality of active areas,
wherein each sub-pixel of the plurality of sub-pixels includes:
a first light-emitting diode (LED) that emits light in response to a driving current;
a first lens that refracts the light emitted from the first LED;
a second LED that emits light in response to the driving current; and
a second lens that refracts the light emitted from the second LED and has a different shape from the first lens,
wherein each sub-pixel includes the first lens and the second lens that is disposed side-by-side on a same layer,
wherein each of the plurality of active areas operates independently in any one of a private mode and a share mode,
wherein, in the private mode, the first LED emits light and the light emitted from the first LED is output with a viewing angle limited by the first lens in a first direction and a second direction transverse to the first direction, and
wherein, in the share mode, the second LED emits light and the light emitted from the second LED is output with the viewing angle limited by the second lens only in the first direction.
