Abstract

A light emitting display device includes a display panel in which a plurality of pixels is disposed, each of the plurality of pixels includes a plurality of sub pixels, each of the plurality of sub pixels includes: a first light emitting diode configured to emit light by a first driving current; a first lens which refracts light emitted from the first light emitting diode; a second light emitting diode configured to emit light by a second driving current; a second lens which refracts light emitted from the second light emitting diode; a driving transistor configured to control the driving currents, and a capacitor which is connected to the driving transistor, and each of an anode electrode of the first light emitting diode and an anode electrode of the second light emitting diode may be initialized to a voltage different from a voltage which is applied to the capacitor.
