Abstract
A display unit capable of being simply designed and manufactured by using more simplified light emitting device structure while capable of high definition display and display with superior color reproducibility and a manufacturing method thereof are provided. The display unit is a display unit (), wherein a plurality of organic EL devices (B), (G), and (R), in which a function layer () including a light emitting layer () is sandwiched between a lower electrode () made of a light reflective material and a semi-transmissive upper electrode (), and which has a resonator structure in which light h emitted in the light emitting layer () is resonated using a space between the lower electrode () and the upper electrode () as a resonant section () and is extracted from the upper electrode () side are arranged on a substrate (). In the respective organic EL devices (B), (G), and (R), the function layer () is made of an identical layer, and an optical distance L of the resonant section () is set to a value different from each other so that blue, green, or red wavelength region is resonated.
