Disclosed are a light emitting display device and a method for fabricating the same. The light emitting display device according to the present embodiments includes a first substrate including a pixel region and a non-pixel region surrounding the pixel region; a plurality of light emitting diodes disposed in the pixel region of the first substrate, and each including a first electrode, a light emitting layer, and a second electrode; and a second substrate disposed to face the first substrate. Also, the light emitting display device according to the present embodiments includes a sealant by coupling the first substrate to the second substrate to encapsulate the pixel region; and a spacer disposed between the first substrate and the second substrate and provided in a non-light emission region arranged between the adjacent light emitting diodes. In this case, the spacer is disposed on the second electrode of the non-light emission region to be in contact with the second substrate.

Light emitting display device and method for fabricating the same

In a method of fabricating organic light emitting diode display, a planarization layer is annealed, cured, provided with an ashing treatment, and surface-treated to reduce roughness of the planarization layer. Therefore, it is possible to improve reduce problems such as a decrease in reflectivity and variation of color coordinates of the organic light emitting diode display due to the roughness of the planarization layer.

Method of fabricating organic light emitting diode display device

A passivation layer formed over and under a first pixel electrode is provided to prevent corrosion of the first pixel electrode of an organic light emitting diode (OLED) display device. The OLED display device includes: a substrate, a first passivation layer disposed on the substrate, a first pixel electrode disposed over the first passivation layer, a second passivation layer disposed over the first pixel electrode, a second pixel electrode disposed over the second passivation layer, an organic layer including an emission layer disposed over the second pixel electrode, and a counter electrode disposed over the organic layer. Each of the first and second passivation layers is formed of one selected from the group consisting of NiCr, AlO, TiO, ZnO and PbO.
