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 (1), wherein a plurality of organic EL devices (3B), (3G), and (3R), in which a function layer (6) including a light emitting layer (11) is sandwiched between a lower
electrode (4) made of a light reflective material and a semi-transmissive upper
electrode (7), and which has a
resonator structure in which light h emitted in the light emitting layer (11) is resonated using a space between the lower
electrode (4) and the upper electrode (7) as a resonant section (15) and is extracted from the upper electrode (7) side are arranged on a substrate (2). In the respective organic EL devices (3B), (3G), and (3R), the function layer (6) is made of an identical layer, and an optical distance L of the resonant section (15) is set to a value different from each other so that blue, green, or red
wavelength region is resonated.
