Abstract

PURPOSE:To raise the contrast between a light emitting unit and a nonlight emitting unit, and to improve the distinction and resolution of a display unit by forming a transparent base coated with a photosensitive colorant passing a light emitted by a light emitting diode. CONSTITUTION:An LED32 is formed on a base 31 formed with a wiring base or lead terminal, and a transparent substrate 34 coated with photosensitive colorant 33 on the display surface side is formed. The colorant 33 transmits a light emitted from the LED32 in response to the light corresponding to the light spectrum of the LED32 of the light emitted from the LED32. This display unit may also be formed of at least two LEDs having different light spectra so that the photosensitive light emitting unit transmits the synthesized light in response to the synthesized light of the LEDs.
