ABSTRACT:
Disclosed are an active matrix type organic electroluminescent display device and a manufacturing method thereof. At least two capacitors having different functions from each other are disposed in a vertically stacked structure within a unit pixel region. When a compensation circuit needing two or more capacitors having different functions from each other per pixel is applied, the two or more capacitors are vertically stacked, thereby preventing the aperture ratio from being lowered due to the increase in the number of capacitors within the pixel.
