1. An organic light emitting display apparatus, comprising:
- red, green and blue pixels which each comprise a semi-transparent electrode, a reflection electrode facing the semi-transparent electrode, and an emissive layer interposed between the semi-transparent electrode and the reflection electrode;
a white pixel which comprises a transparent electrode, a reflection electrode facing the transparent electrode, and an emissive layer interposed between the transparent electrode and the reflection electrode;
red, green, blue and white color filters disposed in correspondence to each of the red, green, blue and white pixels; and
an optical path control layer disposed at least between the transparent electrode and the white color filter in the white pixel.

Abstract
An organic light emitting display apparatus has a hybrid structure in which resonance red, green and blue pixels and a non-resonance white pixel are combined. An optical path control layer and a white color filter which selectively absorbs light having a specific wavelength are included in the white pixel. Thus, the organic light emitting display apparatus has a large viewing angle, low power consumption, and long lifetime.
