Abstract
PURPOSE: To obtain a green display unit which is large in contrast and high in brightness, by providing a filter, with the main transmissive waveform band whose half-amplitude level of the maximum transmissive wavelength is prescribed and the sub-transmissive wavelength band whose transmission factor is prescrived, onto a GaP photo semiconductor element luminescing in green.
CONSTITUTION: Onto base body 1, wiring stripes 2 and 2' are provided, and GaP photo semiconductor element 3 is connected and surrounded with reflector 4 with reflective surface 4a. Next, the concavity formed of reflector 4 is filled with light diffuser 5 of TiO2, SiO2, Al2O3, etc., and green filter 6 is adhered onto the entire surface. In this case, filter 6 is provided with the main transmissive wavelength band which has a peak of the maximum transmissive wavelength 550 to 570nm against the luminous spectrum of the element and has its half-amplitude level of less than 100nm, and the sub-transmissive wavelength band whose transmission factor at 600 to 670nm is 25% at its maximum. Consequently, the transmissive rate in the peak wavelength band can be prevented from deteriorating.
