Abstract: A light emitting display device includes a substrate, a first electrode, a pixel defining layer, a light emitting layer, a second electrode, and a reflective pattern. The substrate includes a plurality of pixels, each including a top emission pixel in a first area and a bottom emission pixel in a second area. The first electrode is in the first area and the second area. The pixel defining layer includes pixel openings to expose the first electrode and reflective pattern openings between adjacent pixels. The light emitting layer is on the first electrode, and the second electrode is on the light emitting layer. The reflective pattern is in the reflective pattern opening and spaced from the second electrode in the first area.
