Abstract
A top emission type white organic light emitting device (OLED) has a high resolution and a wide color gamut, and a color display apparatus uses the same. The white OLED includes a substrate; a reflective electrode formed on the substrate; an organic light emitting layer formed on the reflective electrode; a semi-transparent electrode formed on the organic light emitting layer; and in the white OLED, a wavelength of a resonating mode determined by an optical thickness between the reflective electrode and semi-transparent electrode is shorter than a shortest wavelength in a visible light region of a white light spectrum generated in the organic light emitting layer.
