Organic light emitting display device having multiple films

An organic light emitting display device comprising:

• a first film formed of an organic material, and having first and second surfaces facing each other and a third surface perpendicular to the first and second surfaces;
• a second film formed on the first film, wherein the second film is formed from electrically insulating material;
• an organic light emitting unit disposed on the second film, the organic light emitting unit comprising:
• a thin film transistor formed on the second film;
• a pixel electrode electrically connected to the thin film transistor;
• an organic light emitting layer formed on the pixel electrode;
• a pixel defining film covering edges of the pixel electrode;
• and
• a counter electrode formed on the organic light emitting layer;
• a third film disposed on the second film and covering the organic light emitting unit;
• and
• a fourth film disposed on the third film, formed of an organic material, and having fourth and fifth surfaces facing each other, the fifth surface facing the third film.
