Abstract

Provided is a light emitting display device. The light emitting display device includes a plurality of pixels is disposed in a display panel and 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 including a first light emitting unit which extends along in a first direction; a first lens which is disposed on the first light emitting diode and refracts light from the first light emitting diode; a second light emitting diode including a second light emitting unit which extends along in a second direction which is transverse to the first direction; and a second lens which is disposed on the second light emitting diode and refracts light from the second light emitting diode.

Dependent claims

A light emitting display device, comprising:

a display panel including a plurality of pixels, each of the plurality of pixels including a plurality of sub pixels,
wherein each of the plurality of sub pixels includes:
a first light emitting diode including a first light emitting unit extending in a first direction and a second direction transverse to the first direction, the first light emitting unit extending longer in the first direction than in the second direction;
a first lens which is disposed on the first light emitting diode and refracts light from the first light emitting diode;
a second light emitting diode including a second light emitting unit extending in the first direction and in the second direction, the second light emitting unit extending longer in the second direction than the first direction;
and
a second lens which is disposed on the second light emitting diode and refracts light from the second light emitting diode,
wherein the first and second directions are transverse to a thickness of the display panel.
