Organic light emitting display device and method of fabricating thereof

A method of fabricating an organic light emitting display device, the method comprising:

• providing a first substrate and a second substrate comprising a plurality of pixels;
• forming a thin-film transistor at each pixel of the first substrate;
• forming a first insulating layer on the first substrate including the thin-film transistor;
• forming a color filter layer on the first insulating layer in a pixel region;
• forming a second insulating layer on the first substrate including the color filter layer;
• forming a light compensation layer made of SiNx in a gas atmosphere mixed with SiH4 and N2 on the second insulating layer and made of a material without hydrogen, wherein the light compensation layer comes into contact with a pad of a drain of the thin-film transistor;
• forming a pixel electrode on the light compensation layer of each pixel region;
• forming an organic light emitting unit for emitting light on the light compensation layer;
• forming a common electrode on the organic light emitting unit;
• and
• bonding the first substrate to the second substrate.
