A structure of light emitting diode (LED) effectively reduces its spectral width. The LED structure is applied in a three color mixing of a backlight module to broaden a color space and to improve a saturation of a color display. A grating structure is used as a waveguide layer to coordinate with the LED structure. The present invention does not affect the original thermo and electrical characteristics of the LED structure and has a simple fabrication method.

LED device having reduced spectrum

A silicon bulk-micromachining technology is used to fabricate a GMR filter by exploiting the structure of a suspended silicon nitride (SiNx) membrane on the silicon substrate. A first silicon nitride (SiNx) thin film and a second silicon nitride (SiNx) thin film are formed on opposite sides of the silicon substrate. A first opening is defined in the first silicon nitride (SiNx) thin film, and a grating structure is defined in the second silicon nitride (SiNx) thin film. By etching off a portion of the silicon substrate exposed from the first opening until a portion of the second silicon nitride (SiNx) thin film is exposed from the first opening, a light path space is defined.
