Display unit and semiconductor light emitting device

A display unit, comprising:

• a plurality of semiconductor light emitting devices;
• and
• a dummy device, formed together with each of said semiconductor light emitting devices, for determining an emission wavelength of said semiconductor light emitting device.

A display unit, comprising:

• at least two kinds of semiconductor light emitting devices having different emission wavelengths, which are formed from a common crystal growth layer formed on a common base body;
• wherein electrodes on said base body side form a common electrode.

A display unit, comprising:

• a plurality of semiconductor light emitting devices arrayed on a base body;
• wherein each semiconductor light emitting device has a light permeable region that is formed in a boundary region between two of said plurality of semiconductor light emitting devices.

A semiconductor light emitting device, comprising:

• dummy devices, which are formed around said semiconductor light emitting device.
